Nick Mathewson 1d2c918dfd Move published_on from routerstatus_t to vote_routerstatus_t. 
Nothing breaks here, since all non-voting users of
routerstatus_t.published_on have been adjusted or removed in
previous commits.

We have to expand the API of routerstatus_format_entry() a bit,
though, so that it can always get a published time as argument,
since it can't get it from the routerstatus any more.

This should have no effect on voter behavior.
