main.rs: Open the stream input in Opera

Use the Mac OS X `open` command to open Opera and pass in the contents
of the TCP stream as an argument, assuming it to be a URL that should
be opened in the browser.

Only dealing with the `open` command for now. Will be extending this to
support user-customisable browsers, so that any GUI browser that can be
opened with `open` can be used.
