Add support for --icon flag?

[samdjstevens]

Gulp-notify issues the following command when sending a notification:

notify-send "title" "message" --icon "/var/www/node_modules/gulp-notify/assets/gulp.png"

Which the client then errors with:

Invalid number of options

Can the client accept --icon as well as -i for the icon flag?

I had the same problem today with webpack-notifier plugin within Webpack Encore - --icon was a problem.
