Hack: Use a single-play (non-looping) buffer for very short samples that fit entirely in the buffer for DSound playback. This avoids unwanted repeating of very short samples, but also makes it impossible to extend these selections to continue playback. 

Fixing the real problem could prove to be very hard or even impossible, as it seems to be a problem of timing and possibly even related to the time slices allocated by the OS. As a buffer size in the DSound player is fixed at 150 ms the side-effect of this hack hopefully won't be a real problem.

Originally committed to SVN as r1460.
