Create all Unit Type Abbreviations

[GRUBES]

For the loadout system, we need a mapping of unit types to an appropriate abbreviation that can be used as the value for the s_unitType variable attached to the unit.

We'll basically need a giant list of each unit type and then assign an abbreviation for that type. Similar units might get the same loadouts (e.g. helicopter and fixed wing pilots), so they could potentially share an abbreviation.

Something like:

Unit Type	Abbreviation
Squad Leader	"sl"
Medic	"m"
Fireteam Leader	"ftl"

and so on...

Supports #37

Off the top of my head: Explosives specialists, snipers, AA. Another thing is that they don't really have to line up 1-1 with each unit. Like, what's really the difference between the loadout of a commander and a deputy commander? We could just have an Officer loadout.

You asked for comments and then closed the Issue? :)

Someday for more specialized teams we may need AAT - Assistant AT to carry extra rockets, but that's not an immediate need.

Vehicle and Heli Crew should all be repair specialists so that they have the ability to repair damage.

We will also probably want to create vehicle loadouts.
