Work on extending the framework for accomodating effects.

This extends the framework for being able to handle audio effects, largely
affecting how the audio chain is set up, connected and disconnected, and
therefore the Backend has been refactored slightly, and the class MediaNode
introduced, see its documentation.

In addition two effects has been written: BassBoost and AudioEqualizer.

 * Implement MMF::Backend::disconnectNodes
 This should probably be left for now, particularly until audio effects have been implemented.  This is because the node connection mechanism may need to be refactored slightly once we start building up longer graphs (e.g. MediaObject -> Effect -> Effect -> AudioOutput).
 
+* Before merging, ensure the UID3 is properly allocated, see the .pro file.
+
+* Metadata is not implemented.

+ *   to PlayerUtility, that's it. This means that the order of effects is
+ *   undefined.
+ * - We apply an effect to a PlayerUtility, and MediaObject has that one.
+ *   However, effects might be created before MediaObject, but nevertheless
+ *   needs to work. We solve this by that we are aware of the whole connection
+ *   chain, and whenever a connection happens, we walk the chain, find effects
+ *   that aren't applied, and apply it if we have a media object.
+ * - There are plenty of corner cases which we don't handle and where behavior
+ *   are undefined. For instance, graphs with more than one MediaObject.
