Rename fileElem to urlContainer and fileRegexp to urlRegexp

We are dealing with URL in general, not necessarily with static files on
the server.

Misc fixes

 - use innerHTML instead of textContent, this is how it should have
   been from the start, textContent just worked for Repubblica, as the
   URL was in a script, but what if it is in some html code (<a/>,
   <object/>)?

 - check the regexp actually matches something

repository.
