paper: show branch/tags/bookmarks when browsing (issue3559)

Browse (or manifest) action allows browsing the directory structure at some
specified revision. In gitweb and monoblue styles, the revision header already
has branch/tag/bookmark information for the revision, but in paper style this
header was only showing tags. This patch adds branches and bookmarks.

Branch name needs to be obtained in this special way to be consistent with
regular changeset page, where in paper style default branch is never shown.
