Fixed bugs in HGR, typos in KW, added more KW tanks

- Increased capacity of HGR's conformal tank (HGR changed the model to a
larger one a couple of versions ago and raised the capacity)
- Fixed 200% overcommitment in HGR service module
- Fixed careless typos by this "aristurtle" person that caused two of
the KW 5m tanks to not work
- Added the 5x2 and 5x3 KW adapter tanks
Merge pull request #25 from aristurtle/master
