Unit creation always assigns default equipment

[ibboard]

While working on #54, unit equipment selection doesn't change anything. This is because when a Unit is created it auto-populates itself with default equipment. This is useful for normal "create new unit" situations, but means that "load unit with existing data" situations can end up with equipment that they don't want/need.

Loading default equipment should only be done when we know that it is a new unit because created that needs default equipment.

(In r216) Re #127: Unit creation always assigns default equipment

• Add and use new constructor for Unit that doesn't assign default values

Re #54: Add Army support to WarFoundryFactory

• Load unit name and unit size

r216 appears to fix the problem.
