API improvement

Heya im trying to use the api to prevent muted people from changing signs & writing books. The current api isnt sufficient because it relies on database queries to retrieve this data. This is also required to be done in async mode. Because of this i cant use the database reliably without having to make my own data storage system that should be in litebans.

Can you add a data storage for bans & mutes. This would make my life alot easier. Thanks a tonne.

It'd also be useful to have actual api methods that don't require dispatch a command as that seems like a a->b-c->d instead of an a->d kinda thing.

Awesome plugin, thanks a tonne and keep up the great work <3
