Changes to EarthGrab (PR Fixed, I hope.) (#599)

- 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.
