Changelog:
- Fixed compatibility with Java 16 (done by updating guice to 5.0).
- Fixed some cross-server portal networking issues.
- Fixed deadlock if `PlayerBlockView` fails.
- Fixed issue where walking through a vanilla nether portal would lead to an attempted portal creation back to the origin, causing incorrect portal size and other issues. Now this will no longer attempt to link with BetterPortals, and the vanilla portal will function normally.
- All log prefixes for debug logs are now 3 characters, e.g. `FNE`, `FNR`, `FST` instead of `FINE`, `FINER` and `FINEST`. This makes logs look a little better.
- Added additional API methods to remove portal predicates.
- Portal blocks are now hidden by default!
- Removed fish man.
