Subject: Test to see if we can reduce some crashes by deferring delegate
 destruction until WM_NCDESTROY. This involves adding a specific method to
 allow delegates to destroy themselves to WindowDelegate, and moving all
 delete this calls into implementations of that method (to allow delegates to
 still respond to WM_DESTROY which is legit).
