Small changes to Apple 1 SRAM project

- Added "lock" parameter to 1-pin keyboard driver to allow initialization of (virtual) numlock/capslock/scrollock (the lights on the keyboard don't work with 1-pin communication)
- Changed the SerKbd1TV initialization so it starts with numlock/capslock enabled
- Changed the startup messages slightly
