This commit changes a way we load accounts for profile view:
* instead of using several views with profile controllers, always use
one view to render hooks. This is achieved by redirecting to
individual account page from main profile page (for example when going
into /profile as a user drogus, the effective address will be
/profile/drogus)
* instead of using observers to wait for accounts to load I just use
promise in ProfileRoute#model which effectively ensures that accounts
are loaded at the time we want to select an individual account
* profile controller is split into profile and account controller
Hooks were sometimes not loaded, because user property on
ProfileController was not available. This commit tries one additional
way to get a login - Travis.lookup with controller:currentUser.
Previously we showed only accounts and repositories, to which you have
admin access. To improve usability, it's better to show all accounts and
all repositories, but explain why part of the repositories are not
manageable.
