v1.1.3

- fix new artist_parseable format
issue #44: remove textCapCharacters from key input widget

Keys are mixed case so this just makes it difficult to enter keys.
add Session.clearStations()
change visibility of some of the preference key constants
use a listener to respond to preference changes

The listener will force the default session to update the active credentials
when they are changed and clear station data when it is stale (issue #43).

issue #41: do a better job handling authentication failures

This defines a new broadcast action to send to the NowPlayingActivity.  Due to
the short-livedness of the service it should be the activity's job to notify
the user that reauthentication is required.  If an authentication error occurs,
the session is put into an anonymous state and the user may attempt to use the
app anonymously.

import cleanup
