Issue #7; workaround failure to error handle in Config::Simple
initial commit of CONTRIBUTING.md and add vim modelines to source files
BT #8 apply workaround
update fire script to read husk.conf instead of assuming ipv4/ipv6 support based on /proc
avoid syntax errors causing config files to be overwritten

older versions of bash don't like the [[ syntax in testing, but it would
not error on it. this would cause config files to be overwritten by make
install, particularly /etc/husk/interfaces.conf which was really
annoying. only witnessed on Debain 6.
added option log_late_drop
fix 'common syn' rules

we need to check all flags on tcp packets to make sure syn is the ONLY
flag set, not just check syn only to see if it is set.
resolve bug #10
