API - Colors: Implement full set of colors available from HTML

[bryphe]

We have a very small subset of Colors defined in our Colors module - like Colors.red, Colors.blue, etc.

It'd be great to have parity with the default set in HTML - I think this is a comprehensive list here:

Might be easier with #102 tackled - but it would be awesome to have this full set of Colors in revery, too!

Good place to start looking:
