Comment 1 for bug 1992529

Here is the collab branch: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/collab/sandbergja/lp1992529_npm_vulnerabilities_in_angjs

I needed to make a few changes to the webpack config to get it to build again, notably:
* Using terser instead of uglifier
* Using webpack's built-in chunking, rather than the CommonsChunkPlugin

I did some minimal poking around in the UI, and didn't see any very obvious regressions. I haven't run the test suite yet.

Also, there are still 3 critical vulnerabilities from our dependency on lovefield.
