Dependency incompatibilities between packages are resolved.

Most packages were upgraded to address vulnerabilities.

The autocomplete test was failing due to slow loading CDN package, sometimes up to 40 seconds. I put the static files in a static folder in test for that and after that worked as expected.

I had to change the codeceptjs command since the options muss be passed after the main command

Eslint config had to be updated because the new version introduced new rules that were not enforced before. Also a webpack plugin is used instead of a loader.

Small code refactoring were made to fix some linting errors (var to let, and property name with same value name shorthand)
