Clean up default theme and wallpaper collection

[Pasi Lallinaho]

I just added a new item in the Design SIG wiki.

The Xfce default collection of themes (both GTK and xfwm) and wallpapers
is a bit out-of-date. We really should make it 2011.

This would mean removing a bunch of the old looking themes and include
some new; I'm proposing to include the Shimmer themes, which have had
good feedback when used as Xubuntu default themes.

Yours truly,
Pasi
