Update 1.8.3.3 - refactor code + some bug fixes

Update to version dependency and rollout
If you read my last update, right when decided how to support legacy versions of Minecraft going forward, everything from Spigot and Minecraft changed. Because of these changes, shop versions were going to be much more confusing on which to use for what Minecraft version.

Fortunately, after spending nearly all day refactoring my project and codebase, there can again be simple versioning of Shop.

Shop 1.8.3.3 supports MC 1.14 - 1.18.1
Shop 1.8.3.3-legacy supports MC 1.8.8 - 1.13.2

Easy as that! This is how all versioning will be structured going forward.

(For 1.8.3.3 there will be no legacy build but I will get out a new legacy build soon. For those looking to use shop on 1.8.8 - 1.13.2, you can continue to use Shop 0.8.3.2)

Added LWC compatibility!
For those of you that use LWC, shops now work with protections if you happen to use Shop alongside LWC.

Bugs have been fixed and features have been added!
These all come from the bugs and features you guys have requested on the shopbugs page so keep the bug reports and feature requests coming! Here are the specific ones that this update covered:
