New "stark" theme for Wary

The Wary "5.2 alpha" will have an experimental theme, collectively named "stark".

It is composed of:

Wallpaper: wary_stark.png (rootfs-skeleton/usr/share/backgrounds in Woof)
Icon set: desk_icon_theme_stark042-1.pet (based on area042)
JWM theme: jwm_theme_stark-1.pet
GTK theme: gtk_theme_stark-1.pet

The PETs will be uploaded later.

This theme will not necessarily be in 5.2-final, it is an interesting experiment with, well, starkness.
