Browser Display actor fails for Mac/Linux
Browser Display actor does not detect MacOSX and always uses Netscape for Linux systems. Need to detect the default browser and use that.
for java code that detects default browser and works across multiple OSs

See also ptII/ptolemy/actor/gui/BrowserLauncher.java, which is based
on fairly old code.
It would be nice to have combine code if possible.
