[ale] OT: Execute a URI on winbloze

[Christopher Fowler]

I want to try something on windows.  I want to create an HTML page that
has a link.  I want that link to execute a program with command line
arguments on the windows machine.  

I've seen ActiveX exploits that do this but I want to do it
legitimately.  Here is what I think I need to do:

1.  Load program on client.
2.  Open regedit and create a handler
    for the url.  Maybe I'll call it
    'client://...'
3.  Test it out and see if it works.
