Integration and sample links

Integration improvement (fix musescore#11):
* preprocessor variable to loose the xml and libsnd dependencies
* namespace SfTools
* smallSf now a class variable
* C++11 not needed anymore (struct initialization)
* dynamic declaration of array now ok with visual C++ (fix musescore#10)
* warning and unused variables removed

Bug fix:
* sample links now kept in the soundfont (fix musescore#9)
