Support for gio open on Linux

[City-busz]

On most Linux systems, the gio binary from glib2 package is available to open URLs, e.g.:
$ gio open https://github.com/

It would be nice if this library would be able to use it.

I opened a PR #31. It's a bit more complex, because the gio command requires an additional open argument. I put it before gnome-open, because gio open is meant to be a replacement for gnome-open. gnome-open is deprecated years ago, and cannot be found on modern Linux distributions.

Thanks for your help.
v1.7 was just released, containing the change.
