Adding unit-testing to make mistake-catching easier?

[vm70]

Having to run the game every single time to manually test how things work is a pain. It would be nice if we could configure the PICO-8 to run unit tests automatically for us.

• Does the PICO-8 return anything in stdout when a cartridge runs?
• Has someone already ported the syntax from PICO-8's standard library into vanilla Lua 5.2-compatible code that we can use?

We can use the source code from picolove to implement P8 Lua's standard library for writing unit tests.
