Bring up ThreddsBrowser if USE or FILE called with no argument

Yesterday, while preparing the Ferret-UAF video, the following thought occurred to me: namely that the "natural" way to invoke the THREDDS browser from the Ferret command line (the way that you don't have to look up to remember), is simply to omit the filename argument from the command. Such a command is incomplete and seems to be begging for a UI to help complete it. Thus the THREDDS browser would come up in response to these commands:
yes? use ! user looking for a netCDF file
yes? file ! user looking for an ASCII dataset
What you think of this? Can you think of conflicts that would occur if we took this approach?

It seems possible to add this approach without invalidating the "open" alias or the /BROWSE qualifier. All of these approaches can work together.
