Add authorization to new branch/tag pages.

The create actions have authorization, the new actions didn't,
so no-one unauthorized could actually do anything, but it was wrong(TM).

Update .ruby-version to 2.1.7

Fixes #3835

fixes #3263 slashes are replaced with two underscores

Fixed invalid link on starred projects dashboard.

Fixes #3468

The MR fixes 'Project' links on a dashboard pages headers. See the issue for the details.

This MR does not include tests since the change is rather trivial and there are no (as far as I have seen) existing tests for checking links validity.

In case tests are required I would like to get some guidance on the implementation first. At least I would like to know what should be covered: changed links, all header links, all navigation?

Touch project when toggling stars to update cache

This is a fix for gitlab-org/gitlab-ce#3513.

When a star toggle event happens, we touch project to clear cache key.
This will trigger a new "updated_at" at the project model. If it's undesirable, please let me know and I will try to solve it in a different way.
