* Update lastKeepAliveTime from KeepAliveFrequency (even if that is
disabled).
* Update lastKeepAliveTime from FlyingFrequency too.
* Allow to test for feature tags efficiently.
* lastUpdate is always set calling update().
* Negative diff can not affect update (time ran backwards).
* Use lastUpdate instead of lastAccess where appropriate.
* More comments/formatting.
While we can/could control which stream to log to within onDisable, we
should still assume that an asynchronous task could be using the logging
system. Since we don't have a clean entry to onDisable, we have to catch
the exception.
* Extend CheckConfigFactory with a remove-all method.
* DataManager.clearConfigs() now uses CheckType for getting factories.
* Split off Check.hasBypass method to check exemption + permission.
* Allow null permissions in CheckType (interpret as no bypass).
* Add Check types for FlyingFrequency and SoundDistance.
* Add exemption and actions to FlyingFrequency, alter defaults.
* Add a test for moving a simple config value (not sections).
* Add a flag to @Moved to allow explicitly skipping sections.
(Should enable moving values into a child path of the previous one.)
* Don't set values before inside of processMoved...
First attempt to detect if a moving event would fire. This might not be
100% accurate, as a) we can'T really know and b) lastTo is not minitored
in the most reliable way (e.g. teleport on highest priority, resetting
logic favors set-backs).
* Use a HashMap for data, as we intend to use the primary thread.
* Move redundant move checking into a method.
* Ignore on-ground, if it is sent too often.
* Log if redundant move checking has to be disabled.
Removes access by name and entity-id for now. Access by name might be
re-added, though any kind of mappings will likely be maintained
somewhere near DataManager.
