v3.19.4 (#468)

* Misc cleanup and add snippets (for fun)

* Make site usage report sponsors sort by count descending

* minor cleanup

* Perf optimizations for site usage report.

* Add server-side validation for game start/end, registration start/end, and team size. Resolves #250.

* Don't show plaintext host API key in response (and only optionally update during upsert operation).

* Fix compiler warning

* Fix team game calculation for game center landing.
