version 15:
- complete overhaul of background and foreground color implementation. Now you get a full color picker, and a dynamically generated background that actually works (including custom alpha levels!) on older versions of android.
- fix bug causing some widgets to never update, either when tapped or automatically
- don't display toast messages during background refreshes; only when the users actually taps the widget.


I especially hope you guys like the new color stuff, cause it took a while to get right (but damn you can make some pretty widgets now!)
