Enhanced Color Picker for gpEasy

I would like to replace the existing internal gpEasy color picker with some feature richer one.

Here follows the list of a few very nice pickers:

jscolor - javascript based, smaller size, but needs 5 files.

jscolorXS - this looks cool, only single file, but needs some tests for browser compatibility.

colorpicker - jquery based, bigger size, looks cool but consists of too many files.

jQuery SimpleColor Plugin - small size, similar to current gpEasy picker. Also cool.

Seems to be a dilemma, which picker could suit best for gpEasy.
