Delint and refactor some stuff

- Add devel: true to jshintrc to include browser-present features like
  alert and console.log.
- Bump max func/method name length, no reason to cap this arbitrary low
- Remove moment from event details script (no longer used)
- Ignore invalid names in dev_settings.py
- Remove notimplementedview, which will hopefully never be needed anymore.
- Use a named logger when validating html input
- Some unused imports, splitting long lines, etc.
