making .desktop files executable

# indicates comments in bash, perl, and many other scripting languages. they all cope quite nicely with #! in the first line (by having the interpreter executing the file ignore it)

at that point the desktop files could be executables in any language. they no longer need to be their own special thing.

on *nix you can have an executable called foo and with the #! 'magic' all you need to do is to execute it and the correct helper app is called with no ambiguity. you don't have to name things foo.pl, foo.php, foo.py, etc. (in fact naming things with extentions is likely to cause grief in the long run when you want to re-write a script in a different language, but find that everything else that calls that script includes a file extention in the name that they call)
