Sidebar links are in correct order and link to correct pages

Change CSS to account for new <a> element

Adding links to the sidebar messed up the CSS, so we made a small
edit that made it look approximately as it was before.

Translate page names on sidebar

This adds a new translation domain, 'yelp-endless', in which we
internationalize new UI strings arising from our modifications. New
strings have to go in data/domains/yelp-endless.xml.in, after which
the .pot file must be updated with "make -C data/domains yelp.pot".

Copy existing translations from gnome-help pages

In order to simplify translation, we have copied all existing
translations of page titles from gnome-help that were already
translated.

These translations should still be reviewed. For example, the French
translation is incomplete.
