Happens in 2.06, but not in 2.05.

I noticed that with "com_showSoundDecoders 1" the kneipe_story.wav sound decoder is not shown in 2.06, but is shown in 2.05.
If I enable "s_useOpenAL 1" in 2.05, then it also is NOT shown on the list.
It seems that wav decoders were only shown with non-OpenAL sound system.

However, in 2.05 the problem does NOT happen even with "s_useOpenAL 1".

I measured timing physically.
Used a timer on my mobile, started when I click on "New Game" button.

In all cases the voice ends at 1:27 (a tiny little bit earlier). The sound sample itself is about 1:26.
So the sound part behaves the same way in 2.05 and 2.06, which means that transition to OpenAL is very unlikely the problem.

However, the GUI is working slower in 2.06.
In 2.05, I see the objectives screen at about 1:33.5, while in 2.06 I see it at something like 1:37.5. So here are +4 seconds.

I have fullscreen, experimental stuff off (like multithreading and uncapped FPS).

What is more important:
In 2.05, when sound ends, it does not start over again. I even tried to postpone some GUI events by 6 seconds in the script so that the graphical part were longer: sound did not repeat.
In 2.06, the sound starts playing from the very beginning very soon after it finishes. The sound is not looping, so this should not happen. If it did not happen, then it would be OK, even with a bit longer graphics.

The problem with sound restart is caused by my change due to 0004540.

While the change makes sense for streaming sounds, the engine seems to also have non-streaming ones (very short OGGs and all WAVs). The non-streaming ones were efficiently made looping by the change.

Fixed it in svn rev 7919.
I'm pretty scared of the idea of pushing this to 2.07, so let it start in trunk until 2.08
