Bugfixes and Essential compatibility!

It's been a hot second, and I'm back with some more fixes. Today, I bring to you Essential compatibility, a much better formatting string to text method (see Message counter text), and random tweaks. Please enjoy, and if you like the mod, consider leaving a star! If you have any issues or suggestions, open one up on the Issues page! Until next time...

Changelog:

• build.gradle redo, devenv now has a basic integrations system for testing mod compatibility and dependencies
• now depends on (bundled) MixinExtras, lets Essential work alongside WMCH
• updated fabric api
• updated README and removed example value column
• removed 'propogate lang files' debug option
• random tweaks to some log messages
• added ability for Option instances to be 'disabled' (made initially for Essential compat, but the original process ended up being redundant, so currently it's unused)
• removed most instances of == and replaced them with .equals() for actual functionality
• fixed #32, #33
• made all mixins abstract classes and have only private methods according to common/proper convention
• changed some mixin priorities to be less extreme
• fixed ChatLog logging information under the name 'Option'
• completely overhauled Util.formatString(String) to work consistently and well
• removed unnecessary NAMES string list
• removed useless lang key mutableChat
• added mixin.incompatible lang key for use with the aforementioned Option.disabled feature
• removed Essential from breaks list in fabric.mod.json
