zap2it: Add basic option for language handling

[th0ma7]

Currently in testing to confirm if this solves the parsing error found in #9

If this turns out to run OK, a better option would be to define a configuration file with the list of channels that are in other languages than 'en' so that we can parse that at run time and apply the proper language fields where needed.

In the meantime, this simple fix might turn out ok...

The few bits of changes made it to work!
Adding <icon src= also allowed to get an image to work for all shows.
I may add a few other bits here and there to further align with other standard... but ain't that much of a coder so feel free to chim in..
