| A file chooser for opening packages (with strict behaviour with
| regards clicking on BlueJ packages).
|
| <p>Behaves the same as a PackageChooser but with the added restriction
| that only BlueJ package directories, and archives, are an acceptable
| selection. Double clicking on a BlueJ package will open it rather
| than traverse into it.
