Lucubro July 25-August 7

I spent most of the time on vacation. This is what I've implemented during these two weeks:

• support for loading a score from the hard disk;
• fixed several bugs of the GUI;
• support for a new creative type item;
• implemented SongManager in the client that manage played and stopped songs;
• implemented the client server interactions that allow to play and stop a song (and forward to the near players);
• implemented the client server interactions to request and save the score in the server's database;
• integration testing GUI - SoundManager - network, discovered and fixed several bugs in both;

The musical instrument system is now stable and fully working. The next week I'll make an extensive testing and I'll refine it as much as I can.
