added a method to get fixtures count, primarily for quick stats
Fixed Bug: loopDuration could be wrong

The loopDuration could be higher than the sum of all durations when the
float had more than 3 decimal places.
Implement pan/pitch/volume/loop
Use int for animationInterval instead of long

With an integer a loopDuration of 24 days is possible which is more
than enough. Long is unnecessary big.
 Fixes missing keycodes, cleans up & sorts existing ones.

 An essential/prerequisite commit for further Input improvements, e.g. #2524
