Title: Allow jsx to write tags with bracket, instead of dot, notation.

This will allow for hyphenated tags in the future as something like
`React.DOM["font-face"](content, mountNode)`
instead of the invalid
`React.DOM.font-face.(content, mountNode)`
Many SVG tags have hyphenated tags so this would be a good thing to have.
