FT collision part2: added most of the FT collision system.

Aka "World's most expensive flippers".
This is an aggregate of collision-related changes made during 3DPB->FT transition.
The most important part is in flipper collision - a shift from monolithic iterative solver in TFlipperEdge::EdgeCollision to a distributed non-iterative solver.
Both 3DPB and FT data sets use FT collision, keeping two collision systems does not make much sense.
From user perspective, FT/3DPB systems should not have any major differences.
