Resolve "Simple Approve/Reject Workflow for Raise Requests"

Closes #137 (closed) #221 (closed)

• Removed approve/reject buttons from submitted requests view.
• Put banners to confirm that an action has been taken.
• How many requests left to review is shown.
• A skip button is there to get the next request, the text is changed to "next" if the request has been resolved.

Future improvements to discuss:

• Go back button
• Reverse action button (if someone clicks approve/reject they should be able to reverse this and skip the request)
• Maybe a x/y requests handled instead of z requests left?
