elm_colorselector: Refactored not to change RGBA values many times. 

For example, colors_set changed RGBA five times (The first is in colors_set itself,
the others are in _hsl_to_rgb which called by _rectangle_redraw).

First, this patch splits _rectangle_redraw to 3 separate functions,
_update_colorbars, _update_hsla_from_colorbar and _update_ergb.
So only proper functions will be called instead of _rectangle_redraw.

Second, SIG_CHANGED will be called when RGBA was only changed.
