Matt Kline 68c9d227d0 Default some empty destructors
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.
