Added DBGuids.cs (static func DBGuid.FromDB()
This DBMS-independent function to be used converting UUIDs from whatever format used in the DB (string/binary/Guid). This is mostly needed for MySQL, as in MSSQL they are always UNIQUEIDENTIFIERs and in SQLite always strings (but would look better if we use it there anyway).
