Show XULRunner exception only once
----------------------------------

                 Key: JBIDE-7601
                 URL: https://jira.jboss.org/browse/JBIDE-7601
             Project: Tools (JBoss Tools)
          Issue Type: Sub-task
          Components: Visual Page Editor core
            Reporter: Yahor Radtsevich
            Assignee: Yahor Radtsevich


Now if XULRunner cannot be loaded, the exception appears 3 times (see 3-error-screens.png). It is redundant and not user-friendly. It will be enough to leave only last exception widget (in VPE itself, without any pop-up).
