Bug fixes to AudioLink4Controller, added hue shift to lights & surfaces

This update can be safely imported over top of 0.1.3.

Sliders were drifting around because of a bad setting on the canvas UI, the bug has been fixed!

New feature: AudioReactiveLight and AudioReactiveSurface hue shift (driven by that object's audio amplitude).

Updates to AudioLink core and prefab assets

Updates to the AudioLink core to prevent accidental placement in view of camera, as well as fixes for a serialization issue with some of the prefab assets.
Range slider added to the Delay parameter for prefab components

Minor fixes

Minor fixes to readme and documentation.
