linux: a few small improvements:

* Add PropertyChangeMask to events, makes compiz redraw better with (un)maximizing
* Create the window on the default screen instead of iterating through all of them
* Set backing store hint, looks nicer when moving stuff over the 4ed window
* Set some other WM hints like min/max/default size, gravity, etc since most other
  apps seem to set them
