Start of a color selector. 

Change the last test in e_test.c to #if 1 to play.

Issues:
  Redrawing the H,S and V spectra is a bit slow. Needs to be optimized.

  Spacing / Sizing of the various pieces of the csel widget needs to be cleaned up a bit.

  I haven't actually themed anything yet. Just some fairly basic place holders to get it working. We should wrap each piece in shadowed cutout graphic, and make fancier cursors.

  A color well widget
    - show the currently selected color
    - allows dnd of colors (this probably requires some reworking of ecore selection code)

For anyone wanting to play with this, a single E_Color struct is used by all parts of the selector, preventing the need to copy values around. This includes RGB *and* HSV values since the two spaces aren't 1:1.
