Display saved issue on the front end

[Cleop]

Following #37, we now have new issues saving into the db and on S3. Now we want to be able to display them so that our users can access them.

In order to do this we need to:

• [x] create a page for each issue
• [x] access the copy from S3 and display it
• [x] access the meta data from the DB and display it

For the time being this will not include user data which we have not yet got in our schema.
