- Separated the queue label into a new panel.
- Got rid of the now unnecessary AbstractMap base panel for maps.
- Made the queue label handle overflow (put it in a scroll pane)
- Show a message dialog for when now map can be found
- Machine IDs can now be passed as command line arguments - this
overrides the COMPUTERNAME env var.
- Made the request/cancel methods synchronized instead of using a sync
block inside those methods. This seems to have improved the overall
reliability when mass requests are made, and hopefully fixes the
deadlock that the tutor-client occasionally had.
