title: Export author mapping in Stash SVN Mirror
body: <p>I am building a Stash server to migrate our SVN projects to Git.</p>
  
  <p>Currently I am experimenting with trial Stash and SVN Mirror plugin for importing some of our projects.</p>
  
  <p>The point is the following: while LDAP mapping is working and commits have always been consistent with the users, some people that left the company are no more registered in our LDAP, so I decided to manually type their old email for sake of completeness into the Git Author mapping screen that appears when I prepare the project for importing.</p>
  
  <p>Since it's repeated work, I would like to <strong>export</strong> an author mapping file for the missing entried to import in the plugin's global configuration screen.</p>
  
  <p>The question is:</p>
  
  <p>Do you know how can I export an SVN&lt;->Git authors file from either an existing Git repository made in Stash by an SVN import or <em>during</em> the wizard itself? It could be very useful</p>
