Overlaps with static bodies shouldn't cause blocking

[samme]

Authors may want to check for overlaps with static bodies. That seems to be a valid use. But a positive overlap with a static body also gives positive results for onFloor(), onCeiling(), onWall(), via blocked, which is probably not wanted. (#3691)

Proposal: Body–body overlaps never set blocked.
