[xcode] Support for ALAC encoded RSP/DAAP streaming

Browse Source 
Also changes WAV encoding to use source quality instead of fixed 44100/16/2.
Sets the default to WAV, since it has the best quality, and doesn't have the
delay that creating an MP4 container for ALAC currently has (TODO prepare
the headers to avoid the delay).

Ref issue #1182 and #1665
