GJK endless loops

[ilia-glushchenko]

With sphere-box collision with the precision of 1e-4 and box-box collision with the precision of 1e-10 GJK sometimes gets itself into the endless loop.
Currently, there is an endless loop detection workaround. However, an investigation is needed, in order to remove the source of the problem, or otherwise find and describe the precise reason for it.
