v0.20.1-api5: IT'S HAPPENING!!!

Requires FoxCore v0.10.1-api5

Here it is. Finally an api5 release. It also works with api6 (bleeding builds of sponge). You're welcome.

There's been a LOT of improvements since the last api5 release, and even since 0.20.0-api4.

- Wands are finally fixed.
- Added static handlers.
- Reworked explosion stuff to actually work.
- Big performance optimizations.
- Lots of bugfixes and quality of life improvements.
- Added a flag for hanging entities (Item frames finally get protection now)
- Lots of improvements and additions I probably completely forgot about, but everything should work better-er now.

There's a lot more to come, but I figured i'd make a release for the sake of making everyone happy.

Hope you all enjoy the update!
