Comment 13 for bug 1850473

Okay, another branch: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/collab/sandbergja/lp1850473_ng_lint-2

This takes care of the more than 7,000 issues it found in our .ts files. There are 534 remaining issues in the html files, mainly from the accessibility rules. Please feel very free to push additional commits to this branch, and to rebase it to keep it fresh.
