Changes to Airscooter (#617)

* Changes to EarthGrab (PR Fixed, I hope.)

- Move now has travel time.
- Added particles that travel along the ground, to represent the travel
time.
- Changed the functions of the move to be: Shift + click = grab other -
entity, left click ground = self-grab.
- Edited the default config for the description.
- Edited the default range of the move, changed from 14 to 20.
- Edited the default cooldown time, it is now set to 2 seconds by
default.

* Fixed issues with Earthgrab.

* Add Changes to HealingWaters and Fix for Distance bug (#610)

* Add Changes to HealingWaters and Fix for Distance bug

* Fix conflicts in EarthGrab.java

* Fix conflicts in ConfigManager.java

* Fix conflicts in EarthGrab.java

* Fix for Distance Bug in EarthGrab

* Re-added Sorin's Changes

* Colored EarthArmor + Combo Fix (#608)

• Re-enabled colored EarthArmor, since it works now
• Combos are now created 1 tick later then before. Reason for this is
because if a combo requires the player to be shifting but the last combo
trigger was a shift trigger, the combo would be created BEFORE the
player actually changes shift states.

* Fix Earth Armor and improve Healing Waters (#616)

* Fix EarthArmor and HealingWaters

* Remove commented code.

* Update HealingWaters Description

* Changes to AirScooter

- Particles are now sphered
- Added comments to some areas to explain things
- Tweaked some variables
- Also removed the debug message for "PKListener"
Side note: I wasn't able to find a way to make the player "sit" on the
sphere of air without things getting super buggy. The issues I ran into
while trying to do so: The player's body wouldn't rotate, and the entity
they were riding wouldn't rotate, so their body direction wouldn't match
up with their head. The player was being displayed in a location that
wasn't actually coherent with where they actually where, making the
particles seem off centered. The move would also hesitate to go up and
down blocks sometimes. The player would also appear 4-5 blocks above the
move if they did go up a block a certain way.
