Breaks EventLogging as the old schema is not compatible with these
new properties. We will reapply the patch later when in a better state.
My bad for merging.
This reverts commit ca20031a0e.

This change is an intermediate step in our transition
to logging a variety of events easily.
Also:
* Some events may need sendBeacon support and may not be
logged if the navigator does not support sendBeacon.
* Do not load schema code if EventLogging is not available.
