Reworked functionality of Manual Mode loop. Now, platform must be up and door closed to activate buttons. There is currently no exit from Manual mode.
1. Added and consolidated low pressure conditions in idle loop. Added test to flag a drop in regulator pressure after a normal startup, and also to lock platform in place when gas pressure is lost with a pressurized bottle in place.
2. Added B2 exit to Manual Mode.
3. Added a function for doorOpen(0) routine, since that code is used in multiple locations. Need to do that in more locations.
General Cleanup
1. Changed int to boolean for all states;
2. Added some input reading functions;
3. Cleaned up user LCD instruction text;
4. Changed functionality slightly of pressure sag catch routine.
1. Cleaned up exit of null pressure and pressurized bottle routine;
2. Cleaned up pressure sag routine.
