This reverts commit fbdaf0e2.

Add gitlab-shell to error message to give user a clue that something may be wrong there.

Ran into this in #2082. User was told that repositories were created when they were
not due to hooks symlink being wrong.

This was necessary because this permission is checked dynamically by
`app/views/shared/issuable/_context` when on a Merge Request.

Closes #2058

Unauthenticated users had access to disabled features of public
projects. The code has been slightly refactored so that feature checks
are done in a separate method and can also be applied for public access.

Recalculating graph_log took minutes on a large repository since each
of the 6000 commits would need to calculate the diff. Since graph_log
does not appear to be used, remove it from the list of things to update.
For the Linux kernel repository, this reduced the ProjectCacheWorker time
from 8+ minutes to 16 seconds.

Closes #2016

The label page was added to navigation for unauthorized users because
the previously used milestone read permission was still checked. This
has been fixed and read access to labels is now granted (again) for
public projects.

This regression has been introduced in
07efb17e (7.12).
