What? My commands aren't secure?

- Updated accesstransformer config.
- Added new command processing.
- Introduced the concept of "platforms", like proxies, they have
specific commands tailored to their corresponding side.
- Added entity location helper. Works on the same principle as
getClosestPlayer (actually the same code, but slightly modified) to get
the closest entity to a position.
- Added nf command (testing still)
- Changed getEffectiveSide to getSide.
- Added leftovers from a deleted function that tracked mob spawns and
deaths. (I don't know why this is a feature but you might like to see
how I work)
