Handle the resetting of the jump-amplifier in MovingListener.

Hint at per-velocity friction factor. Could be used to add short term 
velocity that does not decrease. However it can't replace extra-buffer
due to special invalidation conditions.
[Bleeding] Change to lazy ActionFactory setting.

Allows to set a new ActionFactoryFactory without the ConfigManager.init 
already trying to parse actions, thus implementing special actions 
should be easier. Still three calls might be necessary to be on the 
safe side:
1. ConfigManager.setActionFactoryFactory(new factory)
2. ConfigManaher.setAllActionFactories()
3. DataManager.clearConfigs()

Not entirely convinced if concurrency issues might arise with reload or 
even on startup (chat).
Add an annotation for registration order with INotifyReload.

SetupOrder allows to define a priority, so you can register
 ActionFactoryFactory instances before any checks get them.
 
 Default priorities are NCP core at -100, DataManager -80, rest at 0.
Commented that out during testing.
No reason for private here.
