Build fails on case sensitive file systems
The current npm version 1.0.6 fails on case sensitive file systems because `Color.jsx`requires `var Sketch = require('./sketch/Sketch');` but the path is actually `./Sketch/Sketch`.

It is fixed in [master](https://github.com/casesandberg/react-color/commit/23c0c1a4cacb7733d7475874c9751a3e96fac073) so this is actually just a reminder to put it out there :)

Otherwise awesome component!
