Set version to 3.10.13-SNAPSHOT this time.
No need to call super.onLoad.
Comment added.
import time
Simplify and extend AlmostBoolean.
Ra-add the instant-break compatibility code.

For whatever reason it was commented out, it is now put back, assuming
that the reason was "it did not help with mcMMO", because mcMMO used to
fire extra BlockBreakEventS.

Now we use a tri-state and set it to MAYBE if instantBreak is set
already on lowest priority, to have a rough indicator if a plugin set
it, or if the server might have done it. Later we might let FastBreak
assume some maximal duration for either case, instead of ignoring these.
