Add a programming language

[thejpster]

Ideally you would be able to write a game or other application on the Monotron, using the keyboard (or UART input) and without changing the contents of Flash. But what programming language?

• BASIC
• PicoC
• Lua
• MicroPython?
• Monkey
• Something else?

The Flash ROM should provide generic routines (like put_character_on_screen) through a Software Interrupt (SWI) system.

We don't really have the RAM to edit decent sized functions so we need a language we can tokenize / convert to byte code on a line-by-line basis, just like BASIC.

Rhai is an option, but the syntax might need a little tweaking to make it line based.

BBC Basic has some nice assembler support and plenty of examples.

We could also take BASIC and improve it a bit, with arrays and hashes, etc.
