Got the input many hex procedure working correctly.
Got a new user's menu working properly.

Needed up and down arrows, so got this working with the custom character
abilities of the LCD. Re-mapped characters 01h and 02h - will not normally
be printed.
Got led patterns to screen and also free typing mode.

Fixed an issue with pressing ^C before the menu had originally been called.
Fixed an issue with backspace in free typing when deleting the first character
on a row.
Got all debug components working correctly.

Took the reset address information into JdosInt.asm
Fixed the issue with the default interrupt not working. Was storing a
byte instead of the entire word.
Fixed problem with repeating macros. Needed to tell a86 that the label was
later in the file, not looking backwards.
Merge branch 'features/initial-input-service' into development
