Huge batch of bugfixes and a complete rewrite of the orientation portion.
Fixed coordinate system problem with oddly rotated grids
Fixed angular velocity calculation occasional glitch
Fixed upside-down bug that would weird out controls when totally upside-down causing instability
pitchofs= is now fully supported
Fixed some stuff with misaligned thrusters, should be better now, still not perfect perhaps
Fixed not restarting properly after save/load
Fixed some error messages about missing groups and early setup stuff not showing up
Requires much less motion to find planet center due to improved precision calculating
REMOVED support for adjustable pitch and roll angles (for now--pitch may come back)
stripped out all the foreach, hope that helps people with CLR Detected Invalid Program issues.

Big cleanup.
Much better at handling lack of LCD panel in group, now Echos ship scan log to give feedback about what went wrong in more cases.
Added pitchofs={degrees} command. Be careful, there seems to be a bug with the corrector when the pitch (with corrector bias) goes past 90 degrees, causing instability.
Requires much less travel distance to compute the world center.
