[mythtv] XMLTV - DataDirect patch

Here is a patch that enables usage of the datadirect service (labs.zap2it.com). I had to make some modifications to the tv_grab_na_dd that is currently in the xmltv package to make this work (to fully enable GUI interaction). I am going to work with the xmltv maintainer to work this functionality into the final release. For now, though, just overwrite the version of tv_grab_na_dd that comes in the latest release with the one attached here.
Please let me know if this works for you.
I had initially intended to fully integrate this functionality directly into Myth, but ran across several roadblocks, the first of which was the lack of authentication functionality in the QHttp class. It was much easier to use the perl SOAP module which includes this functionality.
Also, this patch does not enable really all of the new potential of the service. I would like to do the following eventually:
* Include the program ID and series ID indicator for improved scheduling ease
* Grab all category information and include in new table
* Get the data all in one fell swoop instead of 13 separate iterations. Also, with the new service, it would be easy/less of a drain to do a complete update of guide data every single day
* Optimize performance -- eliminate the extra XML conversion step, potentially use temporary database tables which would map to the datadirect structures closely
Any other ideas?
Don't be too harsh -- this is my first real efforts in C++ or Qt...
