Update to create method.

Create method now returns an array: $a[0] = response from DBO query() method, $a[1] = the ID of the item that was just inserted.
Socket support.

The Db class is now configured to allow connecting via socket.  The socket parameters are defined in the appropriate ini file and then a simple change is made to $Db::Type property allows you to flip between modes.
