support OnWinButton, OnMinButton & OnMaxButton

... actions in keys.
This allows to override the default behavior as well as adding actions
for the mouse wheel.
Special casing of the two "geometry" related buttons (eg. to perform
smart maximization, reverse the partial maximzation, add shading to the
min button or whatnot)
All other buttons have a rather dedicated meaning and are only really
interesting for adding mouse wheels or eg. the window menu on rmb
clicks.

Needs docu.
