Fix for Bug [805593] MI2: Music stops in LeChuck's fortress
Implemented _cmd_queue save/load. In addition to requiring
_cmd_queue information, this bug arises from a rare assumption
that sound resources are loaded in memory even though they
aren't currently playing. Therefore, a list of sound resources
loaded in memory is included in the savegame, so that all
relevant sound resources are reloaded when the savegame is
loaded. This also fixes an unreported music bug in S&M when
saving a game while outside the Bumpusville mansion.
As a result of savegame format modifications, we are now at
savegame version 23.
