yelp-view: Implement web extension to load resources

I have split the libyelp library into two parts in order to avoid linking the webextension against libyelp. So now we have a libyelpuri with the yelp-uri, yelp-build-uri and their dependecies and the old libyelp with the remaining files. I have modified the yelp-build-uri logic to not have to use yelp-document because it implies to have to add to the new library most of libyelp classes.
