New options

I'm refactoring the code of Coleure in order to provide the following key features:

Edit feature: to change the hue, saturation and lightness or a color (also allowing manual input of custom colors.) Renaming will be possible using this feature as well.

Add to Palette.

Mix & Compare: Right now, people can compare/mix two colors by holding the `alt` key when clicking a color. When I coded that feature, I did it for myself. It's not smart to require a keyboard shortcut in order to use a feature. This new approach will solve the mystery.

UPDATE: Live on site now. http://coleure.com/
