Created an abstract interface for the database handlers.

Renamed CAmDatabaseHandler to CAmDatabaseHandlerSQLite and CAmMapHandler to CAmDatabaseHandlerMap.
Changed std::map to std::unordered_map.
Added to the cmake configuration a definition, which defines the capacity of the source and sink maps.
