Mini bug fix update again for you guys.

Bugs:

- Tank hunters double AT nade ability should now work
- Luftwaffe medic HT cloak should now work at vet 2 & 3
- Retreat to captain should no longer work when heroic charge is purchased
- Calliope can now deploy bulldozer if it has the upgrade
- Various off maps should not longer give out more uses than purchased

As always if any issues arise please post them in the bug board for me.

Enjoy!
