This is a first step in, which doesn't change the default behavior,
however it might break plugins that rely on certain internals.
PenaltyAction allows to do something with probabilities to consider,
including the possibility to select the first applicable penalty or
applying several penalties. There will be player-specific penalties,
which are applied during ViolationData.executeActions always, and there
will be input-specific penalties, e.g. for applying within the event
listener.
Potentially breaking:
* Return value of executeActions is now void for Action + ViolationData.
* Return value of Check.executeActions is ViolationData now.
* CancelAction is now extending PenaltyAction.
* CancelPenalty may cancel, but might not, due to probability.
* IViolationInfo.hasCancel -> deprecated, now returns willCancel().
* IViolationInfo.willCancel is now used, applicable penalties are
estimated on creation of ViolationData.
* Custom actions can no longer be used to cause cancel. Only penalties
can do so now (due to the return type change). CancelAction is still
there to keep a simple action for canceling.
Not yet:
* InputSpecificPenalty support for fight checks and using them in the
default actions.
* Configuration for penalties (currently only a plugin could override
the action factories, later penalties may have a probability to apply,
reference each other, allow first match, apply several at once).
This breaks testing for UNKNOWN_VERSION, if that is used externally.
Access methods are added for testing for unknown versions.
PR mentioning access methods:

* Make attribute methods consistent (remove the sprint boost modifier
from the generic speed multiplier, because it's inconsistent).
* Add missing implementations.
* Adjust default sprinting speed modifier.
* Add more guards for the latest compat module (1.8_R3).
* Add a reflection based compat module for CB, to cover minor updates.
* Possibly other minor fixes/changes.
[Hail "insufficient data written"!]
Contained changes:
- Melon and pumpkin block break timings: 1.8-specific, keep workaround.
- Don't run all horizontal move checking if no move.
- Utility method for checking for air.
- Some formatting.
An implementation for NCPCompatBukkit is missing.
Note that the native access can not set lastYaw nor lastPitch in
PlayerConnection (private), but it could set lastYaw and lastPitch in
EntityPlayer.
Can't guarantee this actually helps with stuff like derp/magnet, because
we can not really set the outcome of a PlayerMoveEvent without
rubberbanding the whole planet. Hacks could send enough packets per tick
to keep freezing people - we might be able to keep track of yaw/pitch
correction and cancel (most) attacking for the same tick after yaw
correction (invalidate "same" with in-bounds yaw).
* 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).
Allow all blocks that get the IGN_PASSABLE flag set but which the player
can stand on to be ground from height 0 on (GROUND_HEIGHT, takes
effect unless for blocks with an explicit workaround). Set IGN_PASSABLE
and GROUND_HEIGHT for ENDER_PORTAL_FRAME explicitly.
Seems better to have a dedicated module for this as well, since other
modules might be built against different versions of the Bukkit-API,
potentially.
