Subject: (svn r7616) -Cleanup:  -(re)set _rename_[id/what] to -1 to catch
 invalid calls (main_gui.c)  -Only invalidate widget of pause/ff instead of
 whole window (main_gui.c)  -Remove numbering from WE_ and WC_ as it's not
 needed, also remove   non-existing windowclasses (window.h, openttd.h)  -Give
 names to some of the enums (window.h)  -In UninitWindowSystem not only free
 malloc'd widgets, but also reset the z-array (window.c)  -Some coding style,
 comments, etc.
