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
