Daniel M. Duley b58843030c Final updates for the new button color implementation. The options class 
now only has one button entry, "ButtonBg", instead of 3. It's up to the client
what to do with it. All the clients are updated except mwm. As the
author noted in his README, mwm isn't Motif window manager at all but KStep ;-)
I disabled it for now until there is new drawing code in there, it would
confuse users anyways since were about to release another Krash and it is
identical to KStep.

Also, I removed the Groove and GrooveText color entries. We now use the
normal TitleBar and Font entries. Hence system will probably look funny until
you adjust the colors since it draws text on the frame and not the titlebar
bg. All the rest look much better by default.

To configure button colors set the active/inactive button background color
in KControl. I'll remove the other entries ASAP. You'll also note that the
active/inactive colors are now actually what you would expect.
