Igor Kushnir e5045860ef Make adding new audio player implementations easy
* add a new interface class AudioPlayerInterface;
* inherit a new proxy class Ffmpeg::AudioPlayer from it;
* partially switch ArlticleView to using the interface;
* expose MainWindow's AudioPlayerInterface instance to all ArticleView
  instances;
* add a new AudioPlayerFactory class responsible for creating instances
  of concrete classes derived from AudioPlayerInterface depending on
  relevant Config::Preferences values;
* increase minimum supported Qt version from 4.5 to 4.6 in README
  in order to use QScopedPointer introduced in Qt 4.6.
