[Catalyst] Catalyst on Windows: fork issues

[Kieren Diment]

Good call.  Lighttpd will be much simpler than  apache, as it's a  
single standalone executable, just run it with lighttpd -f  
my_config_file

Here's a vbs that will get your .bat file that does all of the jiggery- 
pokery running without a cmd.exe window at startup.  I put everything  
in %APPLICATION_DATA% except for this start.vbs script which goes in ~/ 
Startup or whatever the stupid naming convention is in windows.
