[Feature Request] Add audio file configuration to Settings screen

[ai6yr]

Currently, the audio file for receive notification is hardcoded depending on the system you are running, in message_handlers/rx_handler in the function play_sound(). It would be useful to make this configurable within the Settings page. It's also non-obvious to an end user that audio will be played on RX, especially if the hardcoded audio file is not played correctly or missing.

Something that could go with this is an option to limit the number of dings played when a list of new messages are loaded from a node... say, limit to three instead of playing the full 75 dings that were queued up when I came back from lunch today.

LOL, I just ran into this a couple of days ago myself. I've created a separate issue. Thank you.
