[BLEEDING] Testing: ender-pearl glitch use (first sketch, read details).

Browse Source 
* This method is "hard-coded" and not configurable yet.
* Prevent throwing and teleporting into blocks directly, prevent
the second throw on glitching into a one thick ceiling (might lead to
lots of passable violations at present).
* If stuck in a block with the feet (not sand/gravel) without being on
ground, throwing is prevented.
* Some dependencies were updated, hopefully without conflicts for
backwards compatibility (untested).
