Fix for Bug [785373] SAM: Overlapping music at Bigfoot convention

Included the ImDeferredCommand list when checking for
sounds that have been queued to play. Also added
sound queue processing between execution of exit script
and entry script. In the case of this bug, the entry
script required that the iMuse state be fully up to
date, including last-moment changes from the previous
exit script.
