Fixes linter issues

[techieshark]

Fixes #286 (and related to #272).

These commits

• add or update configurations (:wrench:) for lint systems (eslint, csslint, stylelint)
• remove (:fire:) a few vendor files we either get from CDNs or never used
• add config needed for the code climate lint build system (:construction_worker:)
• fix a bunch of lint issues (:rotating_light:) (code climate score goes from 2.4 to 4.0 - a USA grade "C" to an "A").

There's a lot of small changes (whitespace, etc) that should be easy to see are innocuous, and the biggest changes are related to console.log -- we now use app.util.log() everywhere instead, and provide a polyfill for IE 9 and below to ensure we don't get errors from a nonexistent console object. Console logging can be turned off by setting app.debug to false in config.js.

Workflow:

1. Searched by address for a Primary School (Address in Cherrybrook)
2. Returned result - all worked well (Same for Secondary)
3. Clicked "Scroll to top" (a new feature??)
4. Entered a school name (Ferncourt in Marrickville)
5. New school shown - but had old address on bottom:

When searching by School Name this section should not be shown:

This error is in current Master as well. It never used to be there.

OK. So if the reset app state issue is being addressed in another PR then this one of good to go. Merge!
