Class commands, improved sharding, and many other changes (#88)
* Load commands recursively

* Sort commands

* Missed a couple of spots

* missed even more spots apparently

* Ported commands in "fun" category to new class-based format, added babel eslint plugin

* Ported general commands, removed old/unneeded stuff, replaced moment with day, many more fixes I lost track of

* Missed a spot

* Removed unnecessary abort-controller package, add deprecation warning for mongo database

* Added imagereload, clarified premature end message

* Fixed docker-compose path issue, added total bot uptime to stats, more fixes for various parts

* Converted image commands into classes, fixed reload, ignore another WS event, cleaned up command handler and image runner

* Converted music/soundboard commands to class format

* Cleanup unnecessary logs

* awful tag command class port

* I literally somehow just learned that you can leave out the constructor in classes

* Pass client directly to commands/events, cleaned up command handler

* Migrated bot to eris-sharder, fixed some error handling stuff

* Remove unused modules

* Fixed type returning

* Switched back to Eris stable

* Some fixes and cleanup

* might wanna correct this

* Implement image command ratelimiting

* Added Bot token prefix, added imagestats, added running endpoint to API
