Song title display-initial meta classes and UI

Added the initial set of meta classes (but not the proxy code yet),
replaced PeriodicTimer with CountDownTimer.  Removed android support
library. Some View and Presenter class changes to support metadata.
Song titles are working

Song titles are working - some refinements may be needed. Code review
everything again. Evaluate if MetaStreamProxy can be just a single
thread instead of two. Evalulate if startService is an appropriate way
to update the song title.

Deleted TextSwapper (again)
Added preferences support for disabling metadata proxy
Lots of little fixes for metaproxy

IPv6 loopback socket support.  Change connection/read timeouts.
UrlEncode the embedded URL into the metaproxy.  Restart live streams on
disconnect. If we fail to initialize the proxy, fallback to normal
streaming.
