WindowServer: Split double-duty Window::normalize_rect()

Browse source 
This commit:
- merges the two(!) places that defined independently the minimum size of a window.
- splits Window::normalize_rect(), which was originally just a function to apply
  the minimum size requirement, and has taken on the additional job of nudging
  windows back onto the desktop.

This inadvertantly fixes a crash that happens when a malicious program creates a
window of size (0, 0). Now, a window at [0,0 50x50] is created instead.
