Switched to gradle build system
Updated license
Updated Readme
Updated a shit load of dependencies
Removed JDA-Utilities as it was abandonware
Use brigadier command parser
The console can now execute commands
All commands migrated to brigadier
All commands (and their arguments) have suggestions
Commands which send web requests now defer, this should hopefully prevent "Application did not respond" errors.

[x] Move non-RC24 specific brigadier implementations to their own library. (This will help shrink the PR by quite a bit)

[x] Test commands that use database
[x] Register commands globally
[x] Fix bot presence
