MUMUP-2664 : Add in a simple js file to hide bucky if the host doesn't have my.wisc.edu in it



See merge request !10

Standardize and materialize 500, 404, and 403 pages

**In this PR:**
- Removed bootstrap CSS
- Added inline Material Design Lite CSS
- Added a single CSS file for ease of editing, which can be minified and copy+pasted into the inline styles
- Updated CSS (changed old red to new red, removed extraneous CSS)
- Added very basic tab-selection function
- Added sad bucky
- Moved alternate links into tabs (uw-system links are shown by default and uw-madison links can be seen by clicking the uw-madison tab)
- Added `npm` to serve locally for dev purposes
- Updated readme

**Note:** Previously, bootstrap CSS was being brought in via CDN and other styles were added via `<style>` tags. Using the latter approach for MDL looks pretty gory in the HTML. Can I use a CDN for that like we were doing for bootstrap or would that be considered a dependency?
