Add: redstone power event (POWERUP, POWERDOWN) triggers. Also triggers on surrounding (non-powerable) blocks.

* example: WOOL@RED: - {action: POWERUP, sound: CAT_MEOW}
* globalconfig option "redstonewire_triggers_surrounding" in case we need to disable this for some reason
Fix: lightlevel now correctly gets the maximum lightlevel of surrounding blocks (if the target is not transparent)
Add: allow comparatives ("<4" etc, for lightlevel, height, attackrage) to support a range (eg. 1-5).
Fix: allow "ANY" targets to correctly register listeners.
Minor: Eclipse cleanup, comments, debug message improvements
