PulseAudio CLI

On my systems, I always have audio control battles. At the end of the day, I want a single CLI command I can run to raise/lower volume, mute, and get current status. This way I can map these to keyboard buttons or perform them over SSH on all my machines consistantly. I've assembled these three scripts to do that. Note pavolup and pavoldown should symlink to pvctl. The pulse audio sink being adjusted will have to be changed to meet your needs.
