log: use new namespaces api to display names

The only caveat here is that branches must be displayed first due to backwards
compatibility. The order of namespaces is defined to be the 'update' order
which, unfortunately, is not the same as log output order.

It's worth mentioning that the log output is still translated the same as
before since we are formating our strings the same way:

  # i18n: column positioning for "hg log"
  _("bookmark:    %s\n") % bookmark

becomes

  tname = _(("%s:" % ns.templatename).ljust(13) + "%s\n") % name

when name == 'bookmark'. The ljust(13) keeps the strings and whitespace equal.
Adding a new namespace is even easier now because the log output code doesn't
need to change. A future programmer would just need to add the string to the
corresponding .po file (which is the same as they would have had to do
previously).
