title: Can't fetch from private repository with EGit
body: <p>I am trying to synchronise my eclipse java project with my private git repository using EGit plug-in but I'm being unsuccessful. 
  I have configured the remote origin as:</p>
  
  <p>URI: git@github.com:username/project.git</p>
  
  <p>Host: github.com</p>
  
  <p>Repository path: username/project.git</p>
  
  <p>Unfortunately, when I try to fetch, I get this error:</p>
  
  <blockquote>
    <p>git@github.com:Maslor/wfmgr.git: ProxyHTTP: java.io.IOException: proxy error: >Forbidden
    git@github.com:Maslor/wfmgr.git: ProxyHTTP: java.io.IOException: proxy error: >Forbidden
    git@github.com:Maslor/wfmgr.git: ProxyHTTP: java.io.IOException: proxy error: >Forbidden</p>

  <p>I am using a proxy, does that mean I have to configure EGit's proxy settings, if there are any? How can I do that?</p>
