add event to detect and prevent the placement of robots
fix style
make blockTank extend BlockBuildcraft
fix mining well not calling super when placed down
make refinery extend BlockBuildcraft
somehow the old import didn't get removed
filtered buffer wasn't sending blockInteraction event
make it possible to differenciate between the lasertables and engines
detect interaction with pipes (for gates, plugs and robot stations)
also need coordinates for the pipe placement location
make markers and builder send BC block placement events
Set toolClass of ItemWrench to "wrench"

Allows other mods to use the BuildCraft wrench (for things other then rotation) without needing to know the itemstack or implementing the API.
