UE-24528 Fixing focus-distance scaling and focus priority scaling working with concurrency settings.
USoundAttenuation:
- Added methods to SoundAttenuation to get focus, attenuation, and distance scale based on focus factor.
- Added NonFocusDistanceScale parameter to attenuation settings customization so its setable by users
USoundBase:
- Added function on USoundBase which checks IsLooping, which checks the duration
- Removed functions IsAudible and IsAudibleSimple from USoundBase since that functionality is accomplished differently and takes into account focus-distance scaling now.
FActiveSound:
- Caching values of FocusPriorityScale and FocusDistanceScale to Active sound so that can be used for audibility checks
- Included FocusDistanceScale when computing bIsAudible in Active sound
- Moved GetAttenuationListenerData and the accompanying private struct FAttenuationListenerData to FAudioDevice since the audio device and moved code which computes focus factor and geometry into FAudioDevice::GetFocusFactor since it needs to be computed before an active sound exist
FAudioDevice:
- Added SoundIsAudible function which queries a particular sound if its audible based on attenuation settings, focus factor, etc. Will optionally return computed MaxDistance to avoid recomputing it in certain cases.
- Added a few helper functions: FindClosestListenerIndex, GetAttenuationListenerData
- Added GetFocusFactor, which performs the vector math to determine focus factor (0.0 is in-focus, 1.0 is out of focus) for a given sound and listener and attenuation focus settings.
- Updated CreateComponent and PlaySoundAtLocation functions to use the new SoundIsAudible function rather than the old IsAudibleSimple

Change 2815813 on 2016/01/05 by Marc.Audy
Move dispatch of transition functions to new OnMatchStateSet virtual which is called from SetMatchState allowing subclasses to insert their own handling between the set of the variable and dispatch to GameState and Blueprints rather than having to override the entire function.

- Avoid PSC iterating over all particle emitters each tick to check for changes in DetailMode. Now remember global DetailMode when we last checked, and only iterate again if that has changed.
- Add 'WarmupTime' and 'CPUCollision' to Asset Registry Tags for Particle Systems

(4.11) Pass boolean to OnComponentDestroyed that indicates if the entire Actor's hierarchy is being destroyed. If so we can avoid doing a lot of expensive tear down, particularly detaching each component one at a time from the hierarchy and causing massive position/bounds updates.
#rb Zak.Middleton, James.Golding
- improvements to debug drawing - a test can declare which level actors it's using and point at them while being selected in the editor
- added a "comment" field in propertied for a quick summary
