[DS] IF Ground units

I've only got the militia and Emirate forces up so far, still need to do the
IFLF and the various 'special' units.

The first units were easy--I'm cribbing from Command Post Quarterly #5,
which includes the entire Iraqi Order of Battle from Desert Storm in Command
Decision terms, which I translated wholesale. The better quality units will be
much more potent, I can assure you.
