Make the printable_name() function call i18n.t to translate its

output. Makes e.g. "#{name}, v#{object.version.to_s}" which is used in
the changeset browser translatable.

I'm still not happy with how the anchor is constructed. we're linking
from /browse/changeset/1234 to e.g. node "[[366672999, v1]]" even
though the page we're linking to might take us to that node at version
2. The link should be "[[366672999]], v1" instead.

But that's something to solve later.
