Summary: Destroying samples while they're playing crashes

Initial Comment:
Reported by Trent on AD:

"I noticed this on the iphone, not sure if it affects other platforms. I fixed it by adding
al_stop_sample calls before destroying any samples that have been played. I couldn't really find
the root of the problem though. kcm_audio is still swimming in my head, I don't fully understand
it. Just reporting here for reference (Or maybe someone can fix it...)."

Message:
I guess this crash was because al_destroy_sample() was called while a
sample *instance* was still playing that sample. But there could be any
number of sample instances referring to that sample, and we would need some
way to find them. So it's the user's responsibility to stop them; often
al_stop_samples() will do. Added a comment in the docs.

Yes, I just made the same mistake.
