LibGUI: Allow Windows to auto shrink

Browse source 
Previously Windows automatically grew to accomodate layout changes
when obeying minimum widget size but would not automatically shrink
if so desired. Setting auto shrink true now automatically resizes
windows to their effective_min_size() every time their minimum size
updates. This will be useful for making fixed size windows responsive
to layout and font changes in the future.
