Add basic windows pinning

Create WindowPinnableBase class for windows which should be
allowed to be pinned.

Add skin for pinnable windows - currently just a copy of normal
window with 1 extra button (hopefully this can be improved later).

Handle clicking on PinToggle button (pinning/unpinning a window).
