Square display centered and touch handler created.
Increased legibility (eliminated magic numbers and added comments)
Save connected peripherals inside view cells, and update view cells on disconnect
Added debug display on screen for testing bluetooth out of simulator
Added testing buttons for testing fake peripheral drop in drop out UI
Separated TEST and DEBUG shared flags, so testing UI without bluetooth doesn't conflict with debug on screen output
Turned testing off (not needed when bluetooth enabled), and rearranged positioning of menu items
Merge branch 'Usher_Square_Display'
