[web-audio-api] DynamicsCompressor node should enable sidechain compression (#246)

Side-chain compression (http://en.wikipedia.org/wiki/Dynamic_range_compression#Side-chaining) is a very common and useful music production technique.  It's used for ducking (reducing music level while speaking), de-essing, removing plosives, maximizing volume in bass-heavy music, and other techniques.

There are a couple of ways that have been suggested to add this to the Web Audio API: either exposing the reduction as an AudioNode that can be connect()ed to other AudioParams, or exposing a separate input node (with the semantic, presumably, that a separate input node would disable the signal path from the "control" input).
