Plugins: a command ReSkate does not know goes to the game thread, where plugins have theirs

The console answered every command missing from ReSkate's own list itself, as unknown, so a
plugin's command (ptest) never reached the plugins on the game thread. Now only ReSkate's local
commands run there; anything else is queued, and the game thread tries the plugins first and
answers unknown as before when none has it. Checked in game: ptest all, 45 passed, 0 failed.
