2. Magic mode (or busybox, or httpbox mode)

If would be greate if it would be possible to add a new mode
to HTTPie, that works like this:

if the programm was called not using its main main (http),
but using some other name (because the name was hardlinked
or symlinked to http), that would mean that HTTPie should
access the service with that name, and should interpret
its command line options as URL Parameters and pass them to the
service in the URL:

    ln -s $(which http) /usr/bin/wttr.in
    wttr.in Berlin          => (means: http -t wttr.in/Berlin
    wttr.in -0Q Berlin      => (means: http -t wttr.in/Berlin?Q0)

It would allow (using the new framework, that we are currently working on)
expose any service via HTTP/HTTPS and convert HTTPie in a universal
HTTP-based Busybox (httpbox).
