WindowServer+LibGUI: Add per-window progress

Browse source 
Each window now has an associated progress integer that can be updated
via the SetWindowProgress IPC call.

This can be used by clients to indicate the progress of ongoing tasks.
Any number in the range 0 through 100 indicate a progress percentage.
Any other number means "no progress"
