Remove SoundManager2 dependency?

[andyinabox]

I was getting real excited about PxLoader until I saw that the sound plugin is dependent on SoundManager2. It seems unnecessary to have SM2 as a baseline dependency for sound loading for this library, and it's making me reconsider using PxLoader for my project.

Have you considered including a simple sound loader module for basic HTML5 audio, and then a more advanced one that uses SM2 for those who want it?

SM2 is overkill for my needs too, so I'd also like to see this!
