Adds "togglesolar" command to toggle state of the solar alignment module.

Keen's (old) gyro API was changed from rad/s to RPM. Adapt internal API accordingly.

Fix breakage with 1.185.8.

No longer needs a timer block for the PB.

Fix breakage due to center of mass switching from Vector3D to Vector3I in "stable." Thanks, Keen!

Updated the cruise control module. Now accepts "cruise reverse"

Not recommended for use in a gravity well. ;)

Fix any/all usage of deprecated & obsolete API as of 01.172.

Note that the script's "reference point" is now the ship's center of mass.

Added experimental ability to land at a specified GPS coordinate on the ground.

See docs.

Auto-drop minimum speed can now be specified as part of auto-drop command.

VTVLHELPER_MINIMUM_SPEED is still used as the default minimum speed.

Make auto-drop minimum approach speed configurable, enabling rudimentary automated (somewhat safe) touch down.

See the docs for details.
