Displays clickable list of issues that each open in new page. Test passes.

@oliverbarnes : Issue titles are displayed in /issues in a list. The titles are hyperlinked to the individual issue page (e.g. /issues/1) which displays the title and description of the issue.

Do you want this, or do you want the issue to open up under the title as an expandable text when the user clicks on the title?
IssuesIndexRoute and IssueRoute are at the same level in the hierarchy, so I've kept them both under routes/issues. This was Piotr's advice today. I think you were remembering InitiativesRoute, which lives in routes/ and not routes/initiatives because that required some splitting up of the code?
