5dd09d4476 [BLEEDING, INSTABLE] Switch horizontal velocity to a new method. 
This method remembers (currently) each velocity added and only uses it
when it is needed not to generate a violation. Further (currently
simple) activation and invalidation logics are applied. With this method
latency will be much less of a problem, though stacking of queued
entries (especially for rocket-boots style flying) and more
merging of entries and more invalidation logics are required, thus
bleeding+instable.

On the long term this should make cheating much more difficult, possible
steps are:
1. Use method for vertical velocity too (only positive)
2. Distinguish positive and negative vertical velocity (opens a way to
control the speed downwards in any medium!).
3. Per-axis velocity (either absolute or pos/neg with more invalidation
logic on direction changes).

ff409fddea Rearrange some things with MovingListener/PlayerMove(lowest). 
1. Don't check sf if passable sets back already, since passable favours
the
sf-set-back-location anyway.
2. First check which checks to check, to somewhat clean up the
MovingListener
3. Reset some properties on set-back in MovingListener.

036c99653f Use hard limits for maximum number of steps for ray-tracing. 
This concerns both blockinteract.visible and moving.passable, both set
to 60. In effect extreme moves are impossible with either check
activated. Mind that 60 steps could be something like 20 blocks for some
cases, probably even less.
