version 0.20 released

There is now detailed documentation included in the form of a GNOME help entry. Access help by right clicking on the
applet and selecting `Help.' The applet is now sensitive to different panel background types, including background pixmaps. Image quality has drastically
improved due to conversion of the rendering routines from Imlib to GdkPixbuf. Also, on screen sizes with a height less than 768 pixels the moon data box
automatically chooses a 4x4 format which fits better on small screens. The deb was compiled against the latest Helix GNOME version 1.2.8,and the rpm on
Red Hat 7.0 with Helix, so if you're on a pure Debian potato (i.e. GNOME version 1.01 or so) or an older Red Hat system, you'll need to build your own deb,
rpm or binary from the source
