Minor changes.

Implemented persistent tutor client. ...

Hopefully this solves the weird issues we were seeing with the tutor
clients deadlocking.  Will also make the Android client simpler which
should again reduce race conditions.

Made queue label (both fonts and parent panel) resize with frame.

Added map for CO3.17.

Added map for CO3.18.

Removed private project properties from repository.

Scale map fonts when window is resized.

Simplified the timeout when trying to find server. Now applies to all ...

clients - not just the student client.

Code cleanup. Been playing with a few different static code analysis ...

tools.  Used them to recommend the changes made in this commit.

Split out the computer name resolving stuff. Should be easier to add ...

new resolvers if/when ITS start using their random computer names in all
labs.

Added a stress test for the BroadcastResponder.

Clean up. Fixed logging statements, added private constructors to ...

classes that should never be instantiated.  Fixed author names to be
consistent.

Cleanup, and further improvements to concurrency. ...

Should hopefully be bullet proof now.  Seems to handle the stress test
OK.  The tutor client doesn't lose sync during stress test, so hopefully
that problem is now fixed.

Added 'always on top' mode for Tutor Client.

Tweaked tests a bit. StressTest now loops.

Merge branch 'master' of github.com:mgeorge/democall

Initial commit

Changed to mousePressed rather than mouseClicked because clicking labels is a ...

bit weird (seem less tolerant of movement during click than buttons).

Also attempting to fix problem with tutor client occasionally losing sync which
is probably due to threading (maybe server request thread deadlocking).

Added some additional testing classes.

Whole bunch of stuff: ...

- Refactored the map panels to separate the queue label into its own panel.
 - Made queue label overflow without resizing the panels that contain it.
 - Fixed some threading issues by making expanding a couple of synchronized blocks into full method syncs.
 - Added some more constants for things (version number, exit codes).
 - Show message dialog when the server can't be found.
 - Added a test class that causes a message flood for testing threading and queue overflow.

Lots of improvements: ...

- 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.

Added a simple test that simulates all users in a lab requesting help at ...

once.  Tests how the UI responds to overflow in the queue label, and the
general responsiveness and reliability of the system.

Attempt to prevent NetBeans internal project configuration changes from ...

showing up in git.

Stupid NetBeans random project file changes.

Improved TutorClient. Huge refactor. Icon now read from classpath/jar.

Reworked threads, shutdown hook, and exit process to ensure requests are cancelled if student logs/out without cancelling manually.

Added .gitignore for build and dist

Converted buttons to labels on panels. Cleaned up 316 panel. Made server auto-detect which panel to use.

Renamed, and removed some things as a result of refactoring.

Done a whole bunch of stuff: ...

- Added service discovery.
 - Refactored the IMapPanel interface and LabelProcessor to make panels simpler.
 - Numbers now end up in queue label.

Nearly finished.  Need to do testing in labs.
