Replaced jquery.color with the new, modular jquery.colors.

[Enideo]

Fixed the following bugs / requests:

• animate to transparent
  • http://dev.jqueryui.com/ticket/4372
  • http://dev.jqueryui.com/ticket/4635
• expose getRGB and getColor
  • http://dev.jqueryui.com/ticket/3806
• add support for rgba
  • http://dev.jqueryui.com/ticket/5215
• getColor reports inaccurate color for transparent elements in Webkit
  • http://dev.jqueryui.com/ticket/5393

However, the file size has doubled (extra 10kB when minified)!
Still, consider the following points:

• includes all X11 HTML names (previously only 44, now 147),
• rainbow animations easily possible through auto HSL conversion (forward and backwards),
• $.support extended to detect rgba, hsl and hsla color string support,
• rgba is automatically used if supported (progressive enhancement),
• access to the new $.colors utility, useful for many ui developers
  • i.e. RGB, Hex and HSL conversions (strings or arrays).
  • see http://enideo.com/#jquery-colors for more details
• Plus, as $.colors has a modular design, we could remove some parts of it to reduce file size.
  • Also, it can be easily extended by users (i.e. http://enideo.com/#jquery-colors-pickers-hsl )
  • Finally, it's code could probably be optimized better if we try..

PS new to github: first pull request for jquery ui!

Thanks Enideo. Could you split this into several smaller commits so it's easier to review? Also, you might want to fork http://github.com/jquery/jquery-color and send pull requests there as that's the official home for this code, we just pull it into jQuery UI.

Ok I'll try to break it down sometime but a little too busy at the moment.
I considered forking the original jquery-color but what i created grew beyond simple color animation so I felt it had become a different, independent project.
You could check my site to get a quick idea of this new project I've started, it's basically an extendible version of what John did, to reuse max code and allow developers to eliminate what they dont need:

When I've time I'll try to go over the points for my jquery-ui changes

I love this pull request and the associated independent jQuery extension. I needed it to fix jQuery's results when querying the DOM for a color. IE just returns it back exactly as typed in the stylesheet instead of some consistent color object/array. Scott, what would your recommendation be for this library? Even thought jQuery-color and jQueryUI have these services internally (unexposed), do you think it would be useful to have jQuery's css() function to leverage it for true color abstraction? Also, if in jQuery, the jQueryUI and color plugin could just use that directly.

I'm not sure how .css() would be involved. What did you have in mind?
