Run multiple instances of Wireshark.

OS X's GUI-application model is different from the common Windows and UN*X+X11 model; in the former, one process 
handles all open files, and in the latter, separate processes are started for each open file.  In *some* instances, one 
process handles multiple open items - e.g., Web browsers usually have one process to handle all windows, and some 
terminal emulators have one process for all windows.

Wireshark is written for the common Windows and UN*X+X11 model (that's not surprising, as it was originally developed 
for UN*X+X11), and currently can't implement the OS X model - that'd take a significant amount of work.  It's an X11 
application, even on OS X, so to act as a "normal" OS X application requires a wrapper app; the wrapper app we're using 
in the OS X binary distribution appears to be smart enough that if, for example, you double-click on multiple files, it 
starts multiple instances of Wireshark.
