Release 0.51a

Added support for modded parts in some contracts, including:

Antennae from AntennaRange and RemoteTech.

Power Systems from from Interstellar, Modular/Orbital Kolonization, and
Near Future.

Wheels from Firespitter, and landing gears now count as well.

Enhanced state tracking in many contracts, due to a bug in stock code,
docking ports will no longer need to be open, just present, in station
and base contracts. The mod support will also alleviate some confusion
with the "Station Systems" objective. ARM contracts got a practical
overhaul internally, as they were not functioning. Please keep me
updated on if you are able to complete these contracts or not. I am in
testing, but the more feedback the better. Also keep me updated if they
complete for no reason, and when they do so.

No more than two contracts of any given type by Fine Print will appear
on the contract board at any given time.

Aerial waypoints now appear in the same general area. It is still a
decent range, but they will be in the same hemisphere. Aerial rewards
reduced by 25% to compensate.

Rover waypoints now appear in much smaller areas, and there are less of
them. To compensate I have doubled their rewards. Still looking for
feedback on these.

You can now click on waypoints in the main map, this will cause a
navigation icon to appear on your navball to assist you in completing
your contracts. If you have a navigation waypoint set, you can click the
same waypoint to disable it, or it will disable whenever you complete an
objective at that waypoint.

Stations and bases will now occasionally request a cupola viewing port.

Slightly increased the rate at which exceptional station contracts will
ask to be built into new asteroids.
Gave significant station contracts a very rare chance to ask to be built
into new asteroids.

Slightly increased the rate at which exceptional base contracts will ask
for a mobile base.
Gave significant base contracts a very rare chance to ask for a mobile
base.

Aerial contracts should not appear until later in the technology tree,
as I don't think Kerbals can flap two canards fast enough to make it to
the south pole.
