New markup, VERSION constant and update logging

A couple of fixes to make the listing of shows work. 

* Added `VERSION` constant. It was used but not defined. Used the one from [maeckie's repo](https://github.com/maeckie/SVTPlay).
* Updated the xpath for show name to match current web site.

I also removed a bunch of logging of the `VERSION` constant and updated the error logging a bit.

Let me know what you think!
