Bloodfields and Tokens

Fixed a couple of minor issues with the Bloodfields unit lists and army builder
Added new functionality - if you need to reset a tokens rotation after picking it up, press the 'alt' key while holding it
If you want to lock the token into so that it falls straight down and doesn't apply any lateral physics movement hold shift while dropping the token, this will be rolled out to miniatures, terrain, cad, dice, etc later.
