Stable Reworked Audio

- Reworked Internal Audio to work with Streaming Vorbis Files (for now?)
- FlxSound.amplitude, FlxSound.amplitudeLeft, FlxSound.amplitudeRight, SoundChannel.leftPeak, SoundChannel.rightPeak now works. (Streamed Audio on this seems to be half-broken)
- Reworked AudioAnalyzer to work with all type of audios (hopefully) and work with Streamed Audio.
- Redo AudioSwitchFix to work in time instead of when switching states.

gosh, and all that i hope it doesnt break anything.
