Implemented bulk of main functionality for "User Mode" and "Set Mode."  Will go through and double-check later to be sure that all looks as it should.

TODO:
-Comment
-Properly interface with keypad functions
Changed an issue with the key vs. scanKeypad variable.  Added some comments for clarification.
-Added a debouncing delay into the keypadScan()
-Fixed issue with timer not being cleared after 2 second delay in main
-Added another case for bad password in user mode
FIXME: 7 does not print every time, 9 does not print at all, # is printing as 3
DONE:

- Fixed issue in checking system in Check Mode
