Simplify ShowSound() in FileMonitor.cpp.

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.
