New branch: misc-1.9

Hi all,

so there's a new branch in GIT: misc-1.9

What's it about? Well, basically changes in SawfishConfig and (possibly)
integration of thirdparty-scripts (from Wiki).

What's new as of now?

- new widget for SawfishConfig: image (:type image), heavily modified
version of the one recently uploaded
- replaced ancient file-browser with file-chooser-button in file widget
(:type file) (:type file-name) (:type program) (:type program-name)
- added background.jl (as wallpaper.jl), the one recently uploaded to
the Wiki, in a heavily modified version, allowing to additionally also
set the wallpaper for GNOME2 or XFCE4 (though it's main intend is to
have a GUI for wallpaper settings, when using sawfish standalone),
currently missing an option for additional parameters to the wallpaper
setting application, but I'll add that soon

Bugs:

- 'file and 'image widgets don't get serialized => unusable from .jlc
files (quick fix: no wallpaper.jlc)

Planned stuff:

- fix above bug
- more fancyness in UI. As you can see from the attached screenshot, the
'image widget as a way better layout:
  ____
|       |  ______
|       | |______|
|       | |______|
|____|

the three widges are arranged inside a GTKTable (all three), the second
column contains a GtkVbox for the GktFileChooserButton and GktEntry,
thus the much better look'n'feel, compared to most other widgets (see
the lowest option, there the two-line GtkLabel increases the height of
the GtkComboBox). I'll be aiming for all widgets to have a better layout.
