move to scons Clone everywhere rather than Copy; add Session::micro_locate() for ongoing work on video sync; debugging output for export precision problem; minor clean up to IO::find_possible_connection(); fix up a few signed/unsigned issues; make "feature lines" always be the right height as tracks resize; change version to 2.5
