Adds a toggle for software (default) and hardware acceleration for openAL

[Buginator]

In short, with 'Generic Software', we have 256 sources available. With NULL (which means any device) we can end up with 16 HW sources. With the current 'sound *cough* manager', we run into too many issues with onlt 16. (Note, on windows Vista, 'Generic Software' is the default anyway, and you can't get 'Generic Hardware'). Thus, I think forcing Generic Software is a much better option for us now.

On debian, 'Generic Software' fails. That means, we need to default it to true, so linux people can use NULL instead.

Perhaps this should be a menu option?

Default to *true* now, see comment.

Reworked the patch. On linux (& macs?), since openAL is always software, this toggle does nothing. On windows, unless you have a dedicated soundcard, then it should always default to 'Generic Software' (using creative's openAL drivers that we supply via the installer).

Either option you pick, on any platform, if you don't have 'Generic Software', then it falls back to any device available.

My tests on debian show:

---

ALSA Software on default

ALSA Software on Nvidia nforce 2

ALSA Software on Brooktree

OSS Software

Wave File Writer

---

That is with openALsoft.

I wouldn't know which one to pick automatically. So I did the patch the way I did the patch. :)

Hack for 2.1 to select "Generic Software" by default on Windows.

openal-win-software-implementation-hack.patch is intended as a hack to work around this problem for 2.1.

This is more or less useless to all the other platforms except for XP, so, closing this, and sticking with the 'hack' patch.
