During https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/19766,
several usages of these helper methods were mistakenly changed to
instead assign to a (completely unused) local variable.
When `page_title` was misused, for example, this resulted in the page no
longer having a custom title set.
- Split up SnippetsController into separate dashboard and explore sections.
- Use consistent page titles, header titles and sidebars between dashboard and explore sections when signed in or not.
* projects from explore page are available from dashboard
* use dashboard sidebar for both logged in and not users
* move explroe projects under projects tab
* move explore groups under groups tab
* move public snippets under snippets tab
