- Fixed custom weapon generation failures
- Added some #onebattlespell mage filters
- Made unit descriptions primarily triggering of filters (filterdescriptions.txt) and from commands only if no filter explained that command. This is primarily awesome for stuff that gives multiple commands that are describe-worthy. Like glamour always gave stealth and got descriptions for both stealth and glamour. Now it'll just see there's glamour filter applied and tells the filter description and skips the command descriptions.
