- allow SNDINFO to declare sound mappings by using 'sounda = soundfle'.

This works similar to MAPINFO: The first definition in a file declares the format, all later ones must be the same.
This change in syntax increases robustness significantly because it avoids the problems with the original syntax not being able to detect badly formatted names.
