Added variables to control the button select animations parameters
Applied the css animation and filters on buttons when they are pressed,
included the new button animations less into the main file
altered the watch parameters as less wasnt getting rebuilt unless you moddified the main less file and not any of its includes
Modified highlighting to be tied to group coloring, this guarantees that the highlight will never generate a horrible garish color (we know the range of possible group color saturation, so we can make sure the highlight never takes anything over a certain saturation).
Removed vendor prefixes from animation properties, since LESS seems to prefix them (only -webkit- though?)
