重力枪 (Gravity Guns)

Bugs, bugs, and more bugs.

CHANGELOG:
- Changed stereo sound effects to mono since y'all are so opinionated™ on that one
- Sound effects now can only be heard from the user. This is not final and I'm looking into a way of creating a positioned sound source on the user but GeckoLib just has to make this annoying for me. (see [bernie-g/geckolib#171](https://github.com/bernie-g/geckolib/issues/171))
- Removed LDL integration for thrown entities. Unfortunately there's just no way to deduce how thrown multiblock entities should glow or not with LDL's infrastructure. (JMX/FREX support would solve that perhaps?)

CHANGELOG:
- Fluid blocks/waterlogged now cannot be moved
- Might readd support once I've figured out how to handle it
- Added new allow lists (`#gravityguns:mobile`) that **only** allows the blocks and entities on that list to be grabbed (overrides the deny lists)
