Created a new Sound class that does almost nothing :) Useful for
compiling (or running) Stella with no sound support whatsoever. Added ability to compile multiple sound backends into the X11 and SDL versions, and to dynamically select from among them at run-time. For now, the X11 version can't use the SDL sound core. This is in preparation for the ALSA sound backend, which may or may not make it into Stella 1.3. git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@144 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
