Fixed a bug that caused the alarm to go off when replugging the alarm clock when an alarm went off in the previous run

This now sets the RTC's alarm time to 99:99 whenever the alarmState has
been gone through
small change

Made the command array a bit bigger
Alarm changed/RC5 fixed

Changed the alarm code to work with our new hardware
Made sure we wouldn't encounter a hardfault when we'd have recieved 1000
RC5 commands.
Fixed small bug

You can't set the time/alarm to unreasonable values anymore
Fixed another bug

You can now no longer input more than 2 digits while setting the
alarm/time
