React wrapper for Selectize

I have made simple React wrapper around selectize primarily for myself. But if you find it helpful, fill free to use.

And of course fill free to add merge requests or register issues. I will try to handle it as soon as i can.

#Changelog 07.04.2014 Fixed issue when selectize`s dropdown was reopenning after onChange event 10.04.2014 Added ability to pass classes through props ('control-group' class removed)
