Currently all data generated by CM is either in memory only or stored in the configured cache.

For the majority of data this is fine but there are now a few data structures that really should be persistent but are still stored in cache, only due to the convenience of using that data storage mechanism at the time i was developing it. Data that really should be persistent:

• actioned events
• statistics
• last known info on client-server connections
• bot states (event, queue, bot running/stopped and by whom)
• Image fingerprints

Main goals for database support are:

• Support multiple database types via config, interface should be agnostic (should use typeorm for this)
• avoid dependencies on db binaries (I'm looking at you sqlite, use sql.js instead)
• (optional) db access should be async
