Display user name rather than user id
|Reported by:||ema||Owned by:||anybody|
We use Trac and X.509 certificates for auth(z). User ids are DN, so very long strings, useful in pages like Timeline (mainly visited by the admin), but very annoying in other pages like browser, attachments... the Common Name would suffice.
We wish a hack to support usernames, might be computed from the user id, and displaying these shorter names instead of the full user ids.
