Handle jobs that are stored within folders

When items are shown on the main dashboard (/pipelines) they may include items that are from nested folders.
When clicking on an item that is in a folder, it needs to be loaded with the URI reflecting what its folder path is.

In Scope

• When UX-276 is completed we need to handle nested folder jobs in the frontend
• Always use the fullName as the display name
• Browsing to a pipeline should work if its in a folder
• Browsing to a folder should 404
  Browsing to a folder just show a list of the folder contents as if that folder was the "root" of the dashboard

  [1:24 PM] James Dumay: show everything under /org/my/sub/folder/ as it is "/"
