Metadata Search Results Changes ( customize result brief list)

Updated stored procedures to return TWO tables for item information, one with system required information, and another for the aggregation-specific display fields which is set in a field in the SobekCM_Item_Aggregation table
Database search results no longer have hardcoded fields (Format, Publisher, etc..) but rather a lsit of the metadata values
Names of the fields are stored in the Search_Results_Statistics object for display
ResultViewers modified to support this new structure as well
Updated parameter naming and other formatting for several related code files as well ( SObekCM_Database, Brief viewer, etc..)
Laid the foundation for date range searching with the new stored procedures
Merge branch 'master' of github.com:MarkVSullivan/SobekCM-Web-Application
