Implemented incomplete digging



Implemented digging. Will need to be polished and will need to flesh out
the turfs now to make sure that it all comes together well.

Also moved around a few variables and renamed a few, for simplicity's
and conventions sake.
Touch of polish on digging...



So that one doesn't 'Mine()' mobs, who don't have that proc. Instead,
that'll end up being Attack() perhaps. Anyway, that's fixed! :D
Added simple ownership icon...



This way, you can tell at a glance which troops are yours. I imagine it
is useful in every way, and if it isn't, feel free to tell me so I can
remove it/modify it.

Inelegant Digging (Basic) Complete



Digging has now been implemented fully. There are a few issues, which
shall be further discussed in the pull request, but I don't think that
they are decisions that I should make.

Currently, I think it'll work beautifully-- So long as you only have a
single player playing. I expect a large number of fixes will need to be
done once their are multiple players, anyway, and it may be better to try
to grab them all at once.
Selection change and additional work on digging...



Trying to make digging work a bit more nicely with multiple units. Also
trying to make digging work a bit more nicely in general, and possibly
be able to work with multiple people.

Also changed selection so that it allows you to select more units without
great hatred (change of movement) for currently selected units. :D

Quite a bit more elegant digging...



Which allows for multiple units to dig! I think that multiple players will
still need some work, but we can also cross that bridge when getting this
ready for an actual release. Yay!
