title: How do access Bamboo project and global variables
body: <p>I've been using Bamboo for 3 weeks and I'm busy writing a plugin to display build results. One of the things I need to do is generate a pick up location from the global and project variables I've setup but I can't seem to find a way of doing this via a plugin.</p>
  
  <p>I've tried looking at the Atlassian developer forum but I've found nothing useful.  </p>
  
  <p>Does anyone have any experience with Bamboo plugins?</p>
