* recreate date functions from javascript in new class DateTime
* move date and time functions from Util to new class
* fixes various cooldown messages for account recovery
* fix cache id collision when category == dbTypeId for a given dbType
* increment version number to invalidate existing caches
* maps endpoint doesn't need caching. It is entirely static content.
* so we can't directly use BackedEnum::tryFrom as validator, because if
the Enum is of <int> and the string is not what php considers numeric,
we get a straight TypeError Exception instead of null for failing the tryFrom.
