Deploy to other remotes more easily (GustavoFernandes#16)

* Tweak gh-deploy code to facilitate other deploy targets

* Add some packages...

yarn add --dev yargs
yarn add --dev inquirer
yarn add --dev gulp-sequence

* Add prompt and cmd-line arg to deploy to custom remote

* Only prompt when deploying to official site
