Moving empty destructors out of the .cpp files and into headers allows them to be devirtualized in certain cases. (When the compiler can't "see" a function in a header, it must largely assume it's some black box that the linker will resolve.) While we're at it, use C++11's `= default` to define empty virtual desturctors for us. For some classes (e.g., Piano), nothing is derived from it, so we can mark the class as final and remove any explicit virtual dtor. There are many other places where this can be done, but this is a large enough patch as-is.
