Production web site with foundation (WIP)

Initial support for a capable and modern-looking front-end for the Ska web service, including:

- [x] Kadi events browser
- [ ] Kadi commands browser
- [ ] Mica obsid browser (@jeanconn)
- [ ] Telemetry browser (@mathewdahmer)
- [ ] Kadi event web service API

The latter 4 items are not required for this PR.  Still to do for this PR however:

- [ ] Main landing page at root level
- [ ] Top bar navigation
- [ ] Do kadi event listview filtering via pulldown/text box within each column
- [ ] Obsid links to mica pages where relevant
- [ ] *If possible* do twitter-style infinite scrolling of event lists (eliminate paging)
- [ ] Regenerate and remove secret key from public content
