Andreas Kling 1d6ec51bee WindowServer+LibGUI: Add per-window progress
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"
