GtkButton: Use FLAT style class

Browse Source 
This commit makes button always draw background and frame.
Buttons with relief none get a new style class, FLAT, which
allows themes to style these buttons as they like.

We also (finally) mark GTK_RELIEF_HALF as deprecated. It
has never done anything different from GTK_RELIEF_NORMAL.
