Window types

[Rob Adams <readams readams net>]

Lately I've been noticing a lot of programs in HEAD seem to not be
setting the correct window types on their dialog windows.  Dialog boxes
need to set _NET_WM_TYPE_DIALOG hints on their dialog windows.  Metacity
needs these hints to be able to sanely place new windows.  For example,
the gedit preferences window (136933) sets a window type of
_NET_WM_TYPE_NORMAL.

Please go through your application dialog boxes and verify that the
correct window types are being set, especially if you are using glade to
create your dialogs.

I realize that this is quiet late in the release cycle but this is a
very simple to fix yet very user visible bug.
