In #6603 hovercards were activated for logged out users, but they only
worked for local people. Hovercards on remote-people are important to
get the diaspora-id to search the person on the local pod, if you don't
know who it is.
Added search_controller_spec, moved some tests from people_controller_spec to search_controller_spec
Fixed merged conflict in Changelog
update routes and search controller
remove useless except from search controller
Fix indentation in search_controller
* added a presenter for hovercard json
* added new backbone view for handling hovercard JS
* refactoring of PeopleController
* finished the backbone js version of hovercards
* don't try to make people_controller more restfull, out of scope
just add a new route and use that for hovercard json
* added spec for people_controller#hovercard
* add new exception for "AccountClosed" to be able to raise from anywhere
* removed legacy code, since everything got ported to backbone
(except the "cache" stuff, but that's not strictly necessary)
