Raspbery Pi GPIO plugin

Tigerw, such hooks would most probably kill the performance whenever there's a bit more redstone. In this case the polling is actually the better way to go - there's some 16 blocks to poll per tick, compared to possible thousands of hook calls, each having to lock a critical section on a plugin.

However, this does bring me to an interesting idea - how about letting the plugins register callbacks for specific blocks being changed? Something like "If block at XYZ changes, call this function".
