* ext/nas/nassink.h:
Bunch of nassink clean-ups: make build by adding the right CFLAGS
and LIBS to Makefile.am; rename structure, macros and functions
according to canonical naming scheme; move some things around a bit;
use GST_CAT_DEFAULT instead of GST_CAT_* everywhere; remove README
file that didn't really contain any useful information anyway (the
useful bits have been moved into the 'host' property description).

-The nassink plugin
-==================
-
-The nassink plugin is for outputting an audio stream to a Network Audio Server (NCD X/Terminal)
-
-nassink has arguments that it accepts:
- - 'mute'      (boolean value)
- - 'host'      (name of X/Terminal, default is $AUDIOSERVER or $DISPLAY)
