Started work on loading armies

Tiles are starting to look like something that might one day work. Removed the
only tile test, because it was actually wrong even though simple. Also added a
part of the Moloch army. Some other cosmetic changes to BoardLoader -- moved
some code to a separate function.
Started ability parser.
Started modifier parser

Moloch now contains all units and modules, only HQ and instant action tiles
remain.
Moloch fully added, basic parsing complete
Added warnings and errors to army parsing

Also fixed minor bugs there and in Moloch description.
Added logging and errors to BoardLoader

Also small fixes in todolist and grammar ternary magic.
Give out copies of requested armies

Also armies and tiles can now be copied, though the copies contain no
information about owners or observers.
