Lab2 fix

[thawkins83]

I believe this will fix the issue that doesn't allow users to sign up/log in to website using Auth0.

Figured it wouldn't hurt to update the Auth0 lock library.

When running npm install, was getting warnings about vulnerabilities. So updated local-web-server to current version 2.6.1. After that update was done, it defaulted to port 8000 and wasn't using the variable defined as 8100. So instead of Julian needing to re-record the lectures over to use port 8000, I changed variable local-web-server to lws because the hyphens weren't usable in the npm_package variable.
