Below the Surface - fix bugs on password screen

[MHLoppy]

Description

#187 unfortunately introduced the following two minor bugs on the password input screen:

• The console output is flooded with empty lines until a password is entered.
• Moving up from "G" moves to "EXIT" instead of "A".

I've resolved both, though it's possible having the password written to console was leftover debugging and should be removed rather than fixed (waiting to hear back about it) with the console output being removed as Castiel says it was just leftover debugging.

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

I did before/after tests with the fixes applied vs not applied for the following:

• Waiting on the password input screen and monitoring the console output.
• Continuing past the password input screen and monitoring the console output.
• Moving up, down, left, and right for each and every possible input character, as well as for DEL, and EXIT.

Below The Surface - new bugs in password entry screen

Looks good, have compiled and also tested each key, apologies for missing those! As Oscar mentioned with these changes initially, someone may want to tackle changing the way the way the keyboard is generated next trimester(such as a 2D array), as it's a little dodgy using the 1D, especially if anyone adjusts it in future (and the up/down at the W, X, Y, Z are not ideal, but manageable).
