  Added:       src/admin index.html
               src/admin/WEB-INF web.xml
               src/admin/WEB-INF/classes ContextAdmin.java
               src/admin/contextAdmin contextAdmin.html contextAdmin.jsp
  Log:
  Added the admin context - it will be the web-based tomcat admin tool.
  
  Thanks Justyna. The admin context revealed many internal problems,
  we are now able to add and remove contexts at runtime without restarting
  the server.
