Summary:Stateless function components (at least those using arrow functions) are not assigned names when this transform is omitted.

Summary:PR does as it says -- updates Babel dependencies to latest versions.
In general, this changes nothing for 99.9% of users (everyone that isn't FB). If they were to `npm install react-native` right now, they would get all of these dependencies anyway.
However, this does revert a previous change where we were using "~" instead of "^" in front of the Babel deps in order to attempt to lock them to minor dependencies. However, due to the fact that each Babel package uses "^", and there are so many interdependencies, this actually would cause an issue where multiple versions of babel-core, et. al. to be installed.
*Edit* - In addition, we add React to `devDependencies` so that it behaves properly in testing, now that it's a peer dependency.

Summary:This imports `react-transform-hmr/lib/index.js` with a relative path from every module, to make sure we don’t rely on the current (broken) behaviour.
It works now, because:
- the dependency is added by a transform
- we extract dependencies before transforming
- we include `react-transform-hmr/lib/index.js` manually
- packager incorrectly names modules by the name of their package (i.e. packages with multiple versions overwrite each other)
This blocks transforming before extracting dependencies, switching to numeric module IDs, and unbundling/random access bundles.

Summary:
Turns out, even after discussion that was had in https://github.com/facebook/react-native/pull/5294#issuecomment-174397103, we really do need this transform.
I've just included it in the preset...let me know if you all would rather publish to npm.
The actual reason why this is necessary is because in the latest sync from FB, fbjs was updated to use the `Symbol.iterator` express in it's isEmpty function: 064a484e18
We use this in RN in the ListView...and this change (once #5084 is merged) will cause ListView to break on older JSC context's.
This resolves that, and is probably something we should have had all along.

Summary:
Rather than specifying Babel plugins in the `.babelrc` packaged with react-native, leverage a Babel preset to define the plugins (https://github.com/exponentjs/babel-preset-react-native).
This allows for a much better user experience for those who want (or need) to override options in their project's `.babelrc`.
Prior to this PR, if a user wanted to use a custom babel-plugin (or a custom set of babel plugins), they'd have either 1) manually override the `.babelrc` in the react-packager directory (or fork RN), or 2) specify a custom transformer to use when running the packager that loaded their own `.babelrc`. Note - the custom transformer was necessary because without it, RN's `.babelrc` options would supersede the options defined in the project's `.babelrc`...potentially causing issues with plugin ordering.
This PR makes the transformer check for the existence of a project-level `.babelrc`, and if it it's there, it _doesn't_ use the react-native `.babelrc`. This prevents any oddities with Babel plug
