finish up the color selector widgets (plug some leaks)
TODO:
* color_dialog needs a way of specifying initial color
* color_well needs to use this when showing its color dialog
* the grad dialog should remember the last selected colors
* the color dialog whould probably keep a list of favorite / recent colors
Also, it looks like there's a leak (according to valgrind at least) in e_editable.c when you set the text and it reallocs.
