''' Creates an 'Extensions' menu containing two commands:
Open Console Window and Open Explorer.

The Open Console Window command opens xterm on Linux.
The Open Explorer command Opens a Windows explorer window.

This allows quick navigation to facilitate testing and navigating large systems
with complex directories.

Please submit bugs / feature requests to

Current limitations:
- Not tested on Mac OS X ...
- On Linux, xterm must be in your path.
