Removed Vault repo as it seems to be offline and wasn't even used
Fixed CommandSender type, no subcommands handling
Made the default handler use the correct sender type (actually, the generic type might be completely unnecessary but oh well)
No longer checking param types to match methods (needed for generic types)
Fixed/implemented number handling in config
Fixed help text error
Fixed annotation processing in other plugins
Fixed error message on console chat
Fixed CI building (hopefully) - Spigot repo
