started changes to the index_auth page
    
    First round of changes for the index_auth / user dashboard page
    Trying to make it more useful for a user, with icons showing
    the issues and PRs open for each of their repos.
    
    This also has less information about the repos presented
    by default to the user (ntoably the repo description), as
    the assumption here is that the user probably already knows
    what the repo does, because they created it.
