transmitting `mode` query param if present on signedin/notsignedin
Updating "My" user info with twitter infos after a successful twitter signin
TwitterUserInfos should have it behaviour configurable with either :
1/ User infos only
2/ User infos + list of followers/friends ids
3/ User infos + list of followers/friends ids + followers/friends data loaded

By default, a legacy mode is provided with impl number 3/ and a new url is provided for
configurable behaviour
Re-set old impl where only followers/friends ids are fetched, instead of
plain twitter users
I think in terms of performance, it will be better to only fetch one by one
the few people we have in our social network and who use voxxrin
than fetching every friends/followers profiles once (and put it in cache)
Because on twitter users having a big amount of followers/followee, fetching
the complete user profiles might result in a really big amount of data
