Add database plugin

This is to continue on conversation #21 (comment)

Could it be created as a facade, such as only one plugin API (Database) is used by other plugins. But actual implementation of the database would be separate plugins like PostgresDatabase, MongoDatabase?
Maybe it would require two facades, one for NoSQL and another for SQL.

wdyt?

I don't think we need a database plugin. Plugins that need a DB can easily interface with whatever database they want by just importing existing libs.

Hum I see, this Entity Framework Core is nice. So basically, server owners would handle storage of stats/inventory/etc. themself instead of providing a common ground through a plugin?

Yes, persistence isn't the goal of the base framework, this can be handled by plugins.
