Make poezio.core.struct more Cython-friendly.

Status and Command are now slotted classes instead of namedtuples,
which led to a few changes to access them with their named parameters
instead of as a tuple.

“short” being a C type, I renamed Command.short into
Command.short_desc, which is more explicit anyway.

I also renamed possible_show into POSSIBLE_SHOW, as it is a
module-level constant dict.
