[HAO-Tracker-2014-Primary] Removed audio tone related code

- audio tone related code is no longer part of this project since it
has been moved to yasolibs
(https://github.com/sebastienjean/arduino-yasolibs)
- includes and project properties have been fixed in order to compile
against the related static library
- main.cpp has been modified to use the audio tones lib. In addition,
Mario theme player code has been moved in dedicated class (see
MarioThemePlayer .h and .cpp)
