Summary: *This is a PR to fix#1939 (DependencyResolver fails to handle ES6 modules import statements with new lines)*
**This PR includes:**
- A fix to the problematic regular expression
- Updated tests that support the new line style.
**Summary:**
We found out that while the packager does its module wrapping thing for lines like this:
```js
import theDefault, { named1, named2 } from 'src/mylib';
```
It fails to do the same for multi line imports:
```js
import theDefault, {
named1,
named2
} from 'src/mylib';
```
We've tracked done the issue to a [faulty regular expression in replacePatterns.js](https://github.com/facebook/react-native/blob/master/packager/react-packager/src/DependencyResolver/replacePatterns.js#L12)
You can see various import statements with the problematic regular expression [here](http://regexr.com/3bc8m)
We've figure out a better regular expression (you can play around with it [here](http://regexr.com/3bd3s))Closes https://github.com/facebook/react-native/pull/1940

This moves us from warnings on name collisions to errors. If the error happens in initialization it will fatal out.
However, if the error happens while working (after initialization) then I did my best to make it recoverable. The rational behind this is that if you're working and you're changing names, you may introduce a duplication while moving things around. It will suck if you have to restart the server every time you do that.

Since we added packager-managed assets -- internally we still think of asset dependency as a single "module". In reality there are multiple files that represent this module. This becomes important with the `getDependencies` API which is used by Buck to inform it on what to rebuild. Since `getDependencies` deals with modules, and is more of an internal API, I've introduced a new one and would go on to deprecate this.

Summary: In javascriptcore(ios9), this code will run as expected(output 0 1):
```js
for(let i=0; i<2; i++) {
const data = i;
console.log(data);
}
```
But when debug in chrome, the above code will fail without `use strict` prologue (if you add prologue, rn will fail with red screen `Const declarations are not supported in strict mode`): https://code.google.com/p/v8/issues/detail?id=4432.
So it's better to transpile contant by default.

Fix the haste resolution algorithm. Changed the map data structure from a list of modules, to a list of modules grouped by platform.
This considerably simplifies the "getModule" method and makes it easy to properly warn about colliding module names.
This also fixes a bug where we used to include `.web` files when we shouldn't (see task).

@amasad added a warning when there are two @providesModule with the same name. This removes all those warnings by blacklisting the internal version of those files. Once we get of the big react-tools/ hack, we'll be able to remove all those :)

The issue of colliding haste modules have came up many times and have wasted countless engineering hours. This will start warning about it and will also start selecting modules at random so that people don't depend on undefined behavior.
Additionally, this surfaced an issue where with assets we may fatally throw if the directory doesn't exist. This is fixed by checking the existence of the directory before trying to match files in it.

Summary: The `react.displayName` transform was added in 93b9329b758cde3e921b26e11ba91d9700d2a06d.
That diff missed to update the `.babelrc` where the comment says it should stay
in sync (I'm not sure where it's used though). I added a comment in the other
direction so this can be prevented in the future.
I also updated the `cacheVersion` so we actually transform the code again to add
the missing displayName properties to unchanged components.

Summary: Ex. When `console.log` or similar is called, this will call
the original method, which can be quite useful.
For example, under iOS, this will log to the Safari console debugger,
which has an expandable UI for inspecting objects, etc., and is also
just useful if you are using that as a REPL.
I don't believe this incurs a meaningful performance penalty unless
the console is open, but it would be easy to stick behind a flag
if that is a problem.

We swallow errors like it's nobody's business :(
Having an error handler that `reject`s after the promise has been resolved is a no-op. In node, if there is no `error` event handler then the error would throw.
So after we start listening and we want to resolve the promise, we remove the error listener so that we make sure errors actually throw.
Finally, I made the `uncaughtError` handler log `error.stack` so we can get an idea of what's going on.

I've noticed that the logs can be sometimes misleading, as when an Activity ends it doesn't log immediatly. A sync `console.log` would log before it although the Acitivity should've finished before.
Turns out we wait before writing out the logs to the console. I don't see any reason for this. Looking at the `Activity` module it's over-engineered. This diff makes logging sync and simplfies the module.

Summary: I think packager on different platform should generate same output if possible. So packager should replace '\\' in module name with '/' on Windows.

The server dies after 30 seconds if it has no jobs on it's queue. The problem is that the jobs counter gets decreased before returning the bytes to the client. As a consequence, it's possible that the server dies while it's returning the bytes to the client, or just after it finished returning the bytes to the client.
To avoid both issues lets move the counter decrease a few lines below and bump the timer to make sure we have time to fully write the bytes on the socket and let the client close the connection before the server dies.

Summary: There are a few small bugs with the code that launches the editor from the packager:
* First of all, the filepath is not escaped which means tokens like `(` or spaces will mess up the process execution. Dropbox unfortunately decided to use spaces in its enterprise product, so I was getting this error:
![screen shot 2015-07-11 at 3 20 54 pm](https://cloud.githubusercontent.com/assets/1135007/8635748/186e7f2e-27ea-11e5-8058-1f4dabb79634.png)
* Next, the line number argument formatting was assumed to be in a specific format (`:%d`) which actually errors out vim and other editors.
* Lastly, the process was started synchronously but not attached to the stdin / stdout of the parent process. This means that only editors like mvim, sublime, and others would work since they spawn a new window. Editors like emacs, vi, nano, etc wouldn't work and instead just hang at the command line.
So I whipped up this diff to fix a number of these issues, demo here:
