Ported-debugged buhatkj's 3d sound node to irr 1.3.1!

[Dott. Agasa]

Hi all! I did a topic 'cause i had problems porting the 3d Sound Node (OpenAl Based) by buhatkj to 1.3.1. I received no feedback but resolved my problems and updated the node! the biggest "end user" difference is that you need to supply the sound device to the node constructors to ensure correct treatment, else the node might crash 'cause the internal device pointer is pointing to hyperspace. I simplified rendering excluding the node from the render pipeline and doing the changes "on the fly" as there is nothing to be really rendered in the node, and...urr, well, it works.

Here is the package: http://www.mediafire.com/?125mymmxwwn
long lasting mirror, limited bandwidth, zip format, use with care: http://it.geocities.com/megamanx2004200 ... ndnode.zip

I hope this will make someone happy!
