* Meld the following disparate endpoints:
 * `/projects/:id/events`
 * `/events`
 * `/users/:id/events`
+ Add result filtering to the above endpoints:
 * action
 * target_type
 * before and after dates

Previously, `PagesDomain` would not allow a domain such as
123.example.com. With this change, this is now allowed, because
it is a perfectly valid domain.
