Summary: @public
Have a top-level debug namespace: `ReactNativePackager`
And add a couple of debugs in the transformer. This is ground work for adding a verbose option.

Summary:
Fix error in the template string (no plus, thinks it's a function).
And bump the timeout to 30 seconds because a file is taking more than 10 seconds `js/RKJSModules/Libraries/FBComponents/FBFed/FeedStoryFragments.js`
Summary:
There's been a case where Babel can hang indefinitely on a file parse/transform. Possibly related to https://github.com/babel/babel/issues/2211
This adds a timeout to transform jobs and throws an error informing the user of the offending file. The timeout interval defaults to 10 seconds, but can be changed via an option.
Summary:
The cache is only used for JSTransformer at the moment. We're doing IO and some computation to get each module's name, whether is a haste or node module and it's dependencies. This work happens on startup so by caching this value we shouldbe able to reduce the start up time. Lets promote the Cache to the Packager level to be able to use it by any of the components of the packager. For now, on this diff we'll start using it to cache the mentioned fields.
Also we had to introduce the concept of fields in the cache as manually merging the date we had for each path is not possible as we're using promisses all around. With the new API, each field is a promise.
@amasad and I did some manual testing to measure the impact of this change and looks like it's saves 1 second when building the haste map (which represents 50% of the time). Overall this reduces 1 second of start up time which was currently about 8s on my mac book pro.

Previously, we had to use errors as a property on the result object because there was no way to pass custom props between
the child worker and the parent. This has been fixed in node-worker-farm (D2092153) and now we can use regular errors.
This also adapts the transformer to babel-specific errors. Generic errors, however, should still work and render readable
info.
Additionally, I deprecated, but maintained backwards compatiblity for people in OSS that are using custom transformers.
Test Plan:
1. `./runJestTests.sh`
2. `./runJestTests.sh PackagerIntegration`
3. open the playground app
4. Add a syntax error. Say `1=x` somewhere in the file
5. Reload and see error message 'SyntaxError <filename> description (line:col)'
6. Make sure that the stack trace is clickable and it attempts to open the editor to the location
Summary:

Shouldn't confuse the cache from files transformed by different transformers. This takes into account the transformer in the cache hash name.
Test Plan:
* start server with --babel
* generate bundle
* start server with --jstransform
* generate bundle
* compare them and they're different

Fixes [#393](https://github.com/facebook/react-native/issues/393). Currently the transformer assumes line-preserving compilers and defaults to a super-fast source map generation process. However, we need to support compilers that aren't preserving lines.
I had feared this wuold slow down the server but I came about a little known peace of the spec that defines an "indexed source map" just for the purpose of concating files: https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit
Test Plan:
1. runJestTests.sh
2. run server and click around example apps
3. add a custom transporter like babel
4. add a custom file and a debugger statement
5. debug in chrome and make sure it works
redbox still works
