This leaves statics as a way to define static methods and properties
that will be accessible on the return value of `React.createClass`
without changing the current spec.
It is valuable to know when the number of children in a TransitionGroup is going
to increase or decrease, since we might want to apply extra animations.
For instance, when used with overflow:auto, we might want to apply different css
based on it overflowing or not - to do this we need to calculate this after new
nodes has entered and after nodes has been removed.
This moves the static properties off of the root object and into
a 'statics' property. Then they are made available on the constructor so
they can be used directly and in mixins.
Pull request #526 updated the behavior of vendor/constants.js without
changing any source files or the bin/jsx-internal script, so files that
should have been rebuilt (like utils/__tests__/ImmutableObject-test.js)
were not automatically rebuilt (unless you knew to do `grunt clean` or
`rm -rf .module-cache` manually).
This commit allows us to bump a version number when we know the transform
toolchain has been altered in a way that will not be visible to
commoner/jsx.
With this convention, if we reset to an older revision (e.g. during a git
bisect) and the appropriate cached module files are still in the
.module-cache/, they can be used without rebuilding. That's why I prefer
this approach to just deleting the .module-cache/.

Summary:
e.g.
propTypes: {
foo: React.PropTypes.oneOfType([
React.PropTypes.string,
React.PropTypes.number
]);
}
to do this, I exposed a `.weak` chainable validator that returns instead of throws, e.g.
React.PropTypes.string.isRequired.weak
React.PropTypes.string.weak
which returns true or false. Technically, `React.PropTypes.string.weak.isRequired` also exists, but `oneOfType` will never call it. Might be useful to people creating custom validators though.
Since we use keyMirror() and invariant() messages are only shown in __DEV__, we don't have to do manual constant->string translation. Also fixes a few
undefined keys that just happened to work before.
