Adds the "Local Only/kIsLocalOnly" property to sound emitters. Dependent on the kPropIsLocalOnly attribute, which still needs to be added to libHSPlasma.
The commentary about PointerProps and update callbacks appears to be
incorrect. Maybe it was broken in a beta release of Blender 2.79? Works
fine in Blender 2.79b.
This was not completely converted to the new ID Property scheme, it
appears. We have to use an intermediate string property so we can have
get/set callbacks. :(
This sound emitter modifier is almost as fully functional as PlasmaMAX's various sound emitter components. Additional functionality was added to C korlib so that artists can specify OGG Vorbis sound files. If korlib is not compiled, only WAVE sounds can be utilized in Korman. This fixes some of the more fiddly bugs related to exporting to CWE that were seen in PyPRP.
Sound nodes to be implemented...
