Fixed an issue where setting "enable*Regen (* is the type of explosion) to false would not apply.
Now supports CoreProtect (TnTRegen will work with or without the CoreProtect)
Updated the instantRegen method.
Made improvements to the block regen phase for blocks that has gravity.
New configurable options.
shiftGravityUp
If true, during block regen phase, if blocks such as sand & gravel are in the way (possible if example those blocks fell into a crater caused by an explosion), they will be shifted upwards to place down the original block.
maxShiftGravityUp
If shiftGravityUp is true, this is the maximum amount the stack of sand (or other blocks that has gravity) can move up.
Example: If this value is set to 5, only a maximum of 5 sands can be shifted up. If there are 6 or more sands stacked up, they cannot be shifted up.
