Major changes!

This release refactors dtas-player internals and adds lightly-tested
avconv (from libav) and ffmpeg support.  It should also be much easier
for us to add direct support for other non-SoX decoders in the future.

The "source ed" and "source cat" protocol commands now both require a
SOURCENAME argument, one of "sox", "av" (avconv), or "ff" (ffmpeg).
"source ed" also supports a new "tryorder" integer parameter to control
the order in which sox, av, and ff are tried.

dtas-console now displays ReplayGain status and allows controlling
ReplayGain mode, fallback_gain, and preamp values via hotkeys.

There are also many corner-case bugfixes and small minor features, see
"git log" for details.

To install this lightly tested pre-release:

	gem install dtas -v 0.1.I
