Make color selection process have "live" preview
Submitted by Tor Lillqvist
This patch makes the color selector of at least the text tool have an immediately visible "live" preview effect upon the actual text layer visible in the image. This is kinda neat. (But still if one clicks "Cancel" on the color selector, it reverts back.)
As far as I can see there are no ill unintended side-effects. Having to use the block_setting_dialog_color flag is a bit ugly, but without that also the "old" color of the color selector got continuously updated.
