Add TableExtractor by Rob Wunderlich

The Qlikview TableExtractor by Rob Wunderlilch "is a spreadsheet driven
SQL to QVD extract tool. It supports full and delta extracts."

The full TableExtractor is a copyrighted (but free to use) Qlikview
document that can be found at http://robwunderlich.com/downloads/

The script includes and makes heavy use of the GPL Qlikview script
library Qliview-components v6 (http://qlikviewcomponents.org), also
created by Rob.

I have had to make some small changes to this part of the script, which
is why it is tracked here.

So: get the full document from the source if you are interested.
