[Openal] OpenAL Soft 1.12.854 released!

[developer at oldunreal.com]

I need to try yet with the new version, but I converted all ambient 
presets in EFX-Util.h from EAX to EFX, for easy use, so if someone is 
interested or if you want to implement it? I was able to put it into the 
Linux version of my project with that.
I made only some tests with it, but it seems to work as intended. So 
maybe I can give my 5 cent for the project ;)

Also wondering, whats the current OS X implementation status? Had some 
trouble with linking it but even after successfully compiling it 
currently just crashes (need to debug yet why). Is there someone 
actively working on that?
The apple implementation for OpenAL is nonsense in my eyes since it 
requires a lot of rework again and this is truly not the idea of a 
multiplatform solution.
