Move RC2014 recipe in its own folder Also, remove `parts/platforms`. It makes no sense. Only recipes make sense.

; classic RC2014 setup (8K ROM + 32K RAM) and a stock Serial I/O module
; The RAM module is selected on A15, so it has the range 0x8000-0xffff

Add the concept of unit tests Will be much much easier to tests new core routines without having to re-create their context first. Also, extract parse.asm from core.asm

shell/stdio: decouple from blkdev (again) Move load/save to blkdev_cmds and add a new "poke" builtin shell cmd that is the mirror of "peek" and strictly uses stdio (no blkdev involved). This allows us to slim the minimal OS size but, more importantly, change the behavior of "load" so that we don't expect GetC to block until Z is set. This way, using "load X" with X being larger than the blkdev size won't block forever. This also brings our RC2014 minimal kernel below the 1K mark again.

pgm: new kernel module The pgm module implements a shell hook so that when an unknown command is typed, we look into the mounted filesystem and look for a file with the same name as the command. If we find one, we load it in memory and run it.
