[Gimp-developer] request for discussion: removing button relief

[Bill Skaggs]

To follow up for people who don't necessarily look at Bugzilla, this
change has been committed to trunk at Mitch's request, and
Mitch converted it into a style property, defaulting to "no relief" as
shown in the screenshot, so that, should there happen to be
anybody who wants the button relief, they can get it by adding
a line to the gtkrc file.
