Changes

PSG pitch program simplification

Remove "Q trigger" and "PSG after stage" and convert the pitch
start back to height instead of velocity.

The default height is 100m to try to clear most reasonable
launch towers.

The default pitch rate is 5 deg/sec to try to get even high TWR
rockets pitched over quickly.
