Increased truncation for issue titles on milestone#show

Created by: jasonblanchard

Not sure if this is a problem for anyone else, but I find the 40 character truncation for issue titles on the milestone#show page a bit too short. It makes it difficult to browse and keep track of issues on that page.

I've doubled the character limit to 80 characters. I also re-ordered the title div and the user icon div so that it does not get pushed below the title at the first breakpoint.
