Backporting Garrison logic from romanovs-vengeance

[Valkirie]

Backported all the Garrison logic from romanovs-vengeance, without custom content. Right now, e1 (GI) and e2 (Conscript) can garrison. Should address issue #204.

TODO:

• [x] 1:1 backport from Romanovs-vengeance.
• [ ] Fix the fire animation.
• [ ] Fix the fire sound.
• [ ] Don't duplicate traits (AttackGarrisonRV has to be merged with AttackGarrison).

This works surprisingly well in-game. To properly attribute someone elses code: use git commit -m "New Trait - Garrison " --author "Devon Dieffenbach <[email protected]>" on the first commit.
