Re-write of base communication system.

Drones now remember all bases and their positions.
When asked to dock, drone picks the 'best' base to try to dock to. (right now, it's just closest)
The drone then asks that base specifically for an 'approach' waypoint.
If it gets no reply, it tries to move into antenna range of the last known position of the base
When it gets to the approach waypoint, it asks the base for a connector
It then docks.

Use Center of Mass for movement
Use grid name from Remote instead of PB for announced name of ship.

3.0O
update getgrids to NOFOLLOW
Fix crash when attached to print head

3.0P
minor opt in GyroMain
dont go FAST when waiting for reply from dock

3.0Q
localGridFilter in BlockInit
leave LIMIT_GYROS to default

3.0R MDK Version (compressed)

3.0N
code reduction pass
NOTE: Can't dock with something attached to our front (mini cargo) because collision detection 'hits' it..
docking with alignment.

3.0L
04/08: fix crash when being built from projection
rotor NOFOLLOW
ignore projectors with !WCC in name or customdata
ignore 'cutter' thrusters

3.0m
use only stoppingdistance for travel modes/speed
makes for much smoother approach without pulsing thrusters syndrome.

3.0l
check for shorter hitpoints if none are clear. Try to escape to furtherest.
move to half-way to hitpoint and then try again
set forward collision detection based on stopping distance and not target distance (needed for in-asteroid operations)
