python-ps3 get sound support in version 0.1.4

The latest release adds sound support in a simple but nice way. As many samples as desired can be played concurrently and a background thread mixes and resamples them as appropriate.

The library can now be considered to be "minimally functional" complete, as it offers support for fast blitting, controller input and sound. So, most things are now possible and future development will contiue to add features and simplify common tasks (like sprite lists, etc).
