If a window is maximized and has FUNC_MAXIMIZE disabled, still let it unmaximize.  When normal hints change and we reconfigure, the w/h of the window may not have changed - rather the minw/maxh etc may have changed.  So in client_try_configure always run through the code that checks them to see if the client should be resized or whatever.
