Subject: [PATCH] [BUGFIX] Only offer languages with page translation

The link browser listed every language of the site for a page, even
if the page had no translation in that language. Editors could thus
create links to non-existing page translations.

getAllLanguages() now checks which translations of the page exist
and only returns those languages. The default language and "all
languages" (-1) are always kept.
