adding .travis.yml
Working towards 0.8 release
Scans tabards, equips lowest one on entry to instance
Record the currently equipped tabbard, equip it on leaving an instance
Check to make sure Tabard Name and Faction Name match before trying to equip.

Also, TT_equippedTabbard is now a saved variable, not to be overwritten if set.
No more TT_ignored
Now will remove a tabard if none was equipped headed into the dungeon.
A bit more defensive if no tabards are found.
