Added GetAdjustedBestSize which returns the largest of

BestSize and any user specified Min size hints.

Put it to use with wxADJUST_MINSIZE, which now has a chance
of working;  a) if the item gets smaller, and b) with controls
(like wxButton) for whom BestSize and the user MinSize share
only the most tenuous relationship.
