When CFileSystemGCWii::GetFileName can't find a valid filename it would return nullptr.
nullptr as a std::string throws an assert within the std lib.
So return an empty string and check if it is empty or not
Now if more sound types are found, they just need to simply be added to
the unordered set.
- Also changed ShowSound() to IsSoundFile()
- Fixed IsSoundFile’s definition in FileMonitor.h. This whole time it
has been defined as a void method, when in reality it was a bool
function.
- Changed the FileMonitor’s string parameters to be constant references.
