fix in btParallelConstraintSolver to support double precision

Browse Source 
fixes in SAT/polyhedral contact clipping, avoid adding GJK contacts (the contact margin causes different contact depths)
add polyhedral convex shape in InternalEdgeDemo as example of the new SAT/polyhedral contact clipping (added reference to Manual/what's new)
avoid glueing objecs with contacts that are positive (no gaps)
