npm install failing on node 10

There's multiple issues

• gulp failing due to natives missing on node 10
• nsp failing because it is deprecated
• dependencies generally being out of date

I'll create a PR for this so the environment works before I get to look at issue #22

On a likely related note, npm audit in my project is failing due to something in this project. I'm taking a guess it is due to one of the above. Assuming all okay, a release with just the above would be useful to try to fix just that
