Document valid values for -Sound argument

[SkyLined]

It is not obvious what values are acceptable for the -Sound argument; I expect there will be some list of sound identifiers defined by the OS as it does not appear to be a path. It would be nice if the documentation listed those identifiers or linked to a webpage that provides this list.

I just noticed that if you provide an invalid value, the error message will list what appears to be valid values:

Default,IM,Mail,Reminder,SMS,Alarm,Alarm2,Alarm3,Alarm4,Alarm5,Alarm6,Alarm7,Alarm8,Alarm9,Alarm10,Call,Call2,Call3,Call4,Call5,Call6,Call7,Call8,Call9,Call10

Tab completion and/or CTRL + Space should also allow you to select the one you want.

Your absolutely right though that this should be added to the documentation.

It was once possible to do custom audio by pointing to a sound file on disk, but new versions of Windows 10 introduced an issue which broke this and it was very low on the priority list to fix (see #74)
