ansvif 1.6.1

This release includes a -M option for maximum arguments in the fuzz, as well as algorithmic control of ansvif fuzz testing (so that if it has already tried a particular fuzz it will not try it again, this speeds things up quite a bit).

A Windows 64bit .zip, Debian/Ubuntu 64bit .deb, and a Fedora/Redhat/CentOS .rpm are all included in this release.

Happy fuzzing!
