ansvif 1.8

This release includes some touchups to the main ansvif code, better crash detection under linux, as well as our primary new feature: the frontend to ansvif. You can compile it from source with ./configure --enable-gtk or install the compiled .deb, which now also includes the examples in /usr/share/ansvif.
The frontend can be used by running ansvif_gtk. Note that the GTK+-2.0 frontend is under development at this time.
Enjoy and happy fuzzing!
