v0.3-alpha

We're getting closer to dropping that 'alpha' part of the version!

In this release, we've done a large editing pass, looking for wording consistency and simplicity as best we can.

The mechanic for armor has been unified across all unit types, and the old special rule for basic trooper armor has been listed as an optional rule for all units types.

We currently have vehicles in a reasonable state, and I would like to work on ground and flying beasts before making a v1.0.

Also, we'll need a logo before we can release a v1.0!

As always, feedback is welcome as we iterate on the rules and design.
