Minor bug fixes for EXPERIMENTAL_MIDI_OUT. Also added files for autoconf/automake to portmidi and libscorealign. I also modified my local build-related files in src and lib-src to handle EXPERIMENTAL_MIDI_OUT and EXPERIMENTAL_SCOREALIGN, but while I can build with these options, the build-related files are not entirely working, so I will not commit them and break the "normal" builds. I suspect these new build files in this commit are not entirely correct -- some review is in order.
