Update all loadup scripts so that 3 things: 1) call subscripts with /bin/sh so that exec bit need not be set on any loadup script, 2) call medley via scripts/medley/medley.command rather than just medley so that the top-level medley symbolic link is not necessary for loadups and 3) no longer require that the loadup scripts run while cwd is MEDLEYDIR and instead determine MEDLEYDIR from where the loadup script is executed from

scripts/loadup-setup.sh
