Implemented FetchAssetMetadataSet in DB backends.
This method fetches metadata for a subset of the entries in the assets database. This functionality is used in the ForEach calls in the asset storage providers in AssetInventoryServer. With this implemented, frontends such as the BrowseFrontend should now work. - MySQL: implemented, sanity tested - SQLite: implemented, sanity tested - MSSQL: implemented, not tested - NHibernate: not implemented
