The Cancel button on the Edit Wiki page was still redirecting back
to the "Index" page which is no longer the default Wiki page.
This commit changes the Cancel button in the following ways:
* Pressing Cancel while editing an existing Wiki page will now
redirect you back to the latest version of that page.
* Pressing Cancel while editing a brand new Wiki home page that
does not yet exist will redirect you to back to the same Edit
Wiki Home page.
This commit enables the usage of the Gitlab Markdown post processing
on all Markdown formatted files. For file types that do not contain
Markdown, it defaults to the Gollum native renderer to process the
content.
The previously failing Spinach steps have been fixed with this commit.
I have also added new steps that cover the entire usage of the Wiki
system.
The new Spinach steps revealed a minor bug in the Delete page process.
The path for the "Delete this page" button was previously set to
`project_wikis_page(@project, @wiki)` when it should have been
using the singular `project_wiki_page(@project, @wiki)` path helper.
The link has been corrected and all steps are now passing.
This commit replaces the old database backed Wiki system with the
excellent Gollum git based Wiki system.
The UI has been updated to allow for utilizing the extra features
that Gollum provides. Specifically:
* Edit page now allows you to choose the content format.
* Edit page allows you to provide a commit message for the change.
* History page now shows Format, Commit Message, and Commit Hash.
* A new Git Access page has been added with the Wiki Repo URL.
* The default page has been changed to Home from Index to match
the Gollum standard.
The old Wiki model has been left in tact to provide for the
development of a migration script that will move all content stored
in the old Wiki system into new Gollum Wikis.
