Fast Replace

[protocol_1903]

I'm trying to get fast replace working for pipes. As far as I can tell, you need the same collision_mask, boundin_box, and fast replace group per entity. But for whatever reason, that isn't working. What else do you need?

Nevermind, i needed to remove the "fast-replaceable-no-build-while-moving" flag in the data-final-fixes stage instead of data-updates.
