1. Added Manual Mode, which allows user to independently and simultaneously push any combination of the three buttons. Mode is accessible from main menu. The Cleaning switch controls platform up and down. There are no conditionals on the action of the buttons, EXCEPT the clean switch will not drop the platfrom if there is a pressurized bottle.
2. Made buzzer for open door while bottle pressurized continuous.
COMMITTED WITH PROBLEMS: This version is really unstable. Not only does LCD not update; now, actual core functionality is broken.
1. Fixed problem with menu-related strings maxing out 2k dynamic memory space. Used PROGMEM (with some undocumented sytax revisions) to move static strings into flash program memory. There are still a few menu issues, but looking good. Also moved PROGMEM declarations into head of program, before Setup ()
