Removed SQLite DLL dependency

Removed the unneeded using statement for System.Data.SQLite which
required a dependency on the 3rd party SQLite DLL.  This using wasn't
required to compile so no need to require the dependeny on a 3rd party
DLL.  Now the only dependency for all Massive files is .NET 4.0 or
higher.
