Fixed a bug - when returnfield_id is not found in xml_returnfield, records are not added to xml_queryresults

Modified the upgrade java script to provide more effective feedback during the
nodedata copy operation so that users don't think it has failed or crashed.

Modified the code so that lastid file is created in a skin when lastid file is not found.
Commented out the code which uses AdminDB module and uncommented the test function.

1. removed the call to QuerySpecification.printAttributeSQL() from QuerySpecification.printExtendedSQL()
2. in QuerySpecification.printExtendedSQL() if ( returnFieldList.size() == 0 ) then it returns null
3. DBQuery.addReturnfield() doesnt execute the element query if printExtendedSQL returns null

A minor change from containAtrributeReturnField to
containsAttributeReturnField

I've added in a test in QuerySpecification.printExtendedSQL that checks
to see if attributes, and sometimes only attributes, are in the original
returnfield request. If so, the printAttributeQuery is called.

Changed the handleReturnField() method so that it handles path expressions with
only attributes in the path.

Added a check if printAttributeQuery() for returnPath to see that it is not null so that that this doesnt happen

xml_index.path like 'null' AND xml_nodes.nodename like 'id'

Fixed a bug in previous commit

Modified code for computing the returnfield string - earlier only elements were used to construct the string. e.g. /dataset/title
Now attributes are also added to the returnfield. e.g. title/@id
