2.0.0.50

Removed all code having to do with the one-millionth patron countdown.
This code contained poorly formatted logic resulting in slow runtime.

Also added the functionality of an exit button at the password prompt.
Previously there was no way to exit the program if a user did not know
the password without crashing it.

(Also note the previous version was 2.0.0.49, not 1.0.0.49 as was
documented in the previous commit.)
