[docs] Fix a broken link to JSX syntax in README.
#JSX => #jsx
Add bitwise lint escape to DefaultDOMPropertyConfig
Ensure attribute values are strings

`jsdom` behavers differently than browsers here and we should ensure
that we are consistent. Browsers should be (and are) converting to
a string first, while `jsdom` doesn't.
Standardize prop -> DOM attribute process

Allow more than strings and numbers to be used as attributes for DOM
nodes. This removes the special casing for `0` and `false` that was
being used in ReactDOMInput and ReactDOMTextarea.

Now we will just `toString` any object we try to insert into a DOM.

Closes #422, #372, #302
Be consistent with object naming in tests

This also fixes line length issues our linter was complaining about.
Make sure DOM components work in JSDOM

Fix Lint

Enabling bitwise linting caught another user. Also fixed a semicolon
misuse.
Use getActiveElement module

We had something that did the same sort of protection. The module
differs slightly (returns document.body instead of undefined) but
looking at the callers, that should be ok.
