This fixes sound corruption when using the new VOC streaming code. It also reduces the runtime memory needed for compressed sound files slightly, since it does not preload them into memory anymore. This comes at the expense of one file descriptor needed per sfx being played though. Thanks to Kirben for his review and feedback.
