patch to remember user theme directory

[Tim Macfarlane <timmacfarlane blueyonder co uk>]

This patch to gdmsetup.c lets the Graphical Greeter tab remember where
the user last installed a theme from (just for one session). When
installing lots of themes I was annoyed that the file chooser always
went back to the cwd, not the last one selected.

I'm a virgin GTK user so I'm not sure if GTK file chooser has an option
for this already, so the patch just stores the last directory in a
global user_theme_dir.

the patch is attached.

timbo.
