Minor UI improvements

Candidates now get an easier option to go back to the the previous question. Instead of the back button being at the bottom left of the screen, it's now at the unmissable top right corner as well.

In-progress applications now show the "Draft" status of responses as well - this occurs when candidates have recorded an answer but have not hit the Next/Submit buttons.

Right clicking on the dashboard job titles - now allows you to open the job details page in another link.
