type Database 

type Database struct {
	DB                  *sql.DB
	Writer              sqlutil.Writer
	Invites             tables.Invites
	Peeks               tables.Peeks
	AccountData         tables.AccountData
	OutputEvents        tables.Events
	Topology            tables.Topology
	CurrentRoomState    tables.CurrentRoomState
	BackwardExtremities tables.BackwardsExtremities
	SendToDevice        tables.SendToDevice

}

Database is a temporary struct until we have made syncserver.go the same for both pq/sqlite For now this contains the shared functions
