Update dependencies and devDependencies #44
Description
Is your feature request related to a problem? Please describe.
Including htmlhint-loader in a webpack project results in a lot of deprecation warnings at npm checkout time
Describe the solution you'd like
A pass through packages.json to see which dependencies and devDependencies can be upgraded without breaking things and upgrade them. I can likely make this PR if it will be accepted. I see that bot-submitted PRs for updating things are being rejected.
Describe alternatives you've considered
