ReactTools is deprecated, it doesn't belong at the root of the project. We'll remove it after 0.14 but for now this moves it so that it's contained and not intermixed with the rest of the project. The currect behavior of copying src/ into the package is maintained.
This reworks a few things in building and distributing React. The biggest change is using fbjs to share dependencies with other libraries. We're also using Gulp for some build steps.
Rely on jest for now until we get a better and less hacky solution to running tests in the browser, probably a totally different test suite with different behavior/goals.

Differences mostly look to be various bits of whitespace that Babel ends up removing during its transforms (https://gist.github.com/spicyj/21ef31f4d95fb7a58daf). In minified files, mostly additions of `"use strict";`.
Valid values are 'es3' and 'es5'.
es3: perform reserved words quoting, don't use defineProperty
es5: default, don't do the above, class methods non-enumerable
We were doing some preprocessing for module options in the command line. Since
we also expose the same API via react-tools (and JSXTransformer), we need to do
the same processing from the API. So just move it all to the same place.
We will continue using `bin/jsx-internal`, well, internally.
Note that this version no longer respects `@providesModule`, and it
doesn't do anything special with constants like `__DEV__`, so we can no
longer get to claim that `bin/jsx` can be used to build the core.
I'm happy about this, personally, because it demonstrates the flexibility
of Commoner.
No longer injecting __MOCK__ as a global constant (it's just a config
property now).
Turns out the `grunt jsx:debug` task was never necessary for tests.
