[request] Option to set a "playlist folder" that Tauon will write playlists to AND read from

[rexendevar]

I'm trying to set my system up so that in addition to music being synced between my phone and my computer using Syncthing, my playlists also are synced. This involves being able to edit m3u files on either device, as well as these files being loaded in automatically. On my phone this is relatively easy, as my mobile music player supports loading m3u playlists as well as writing to them - playlists can be made fully and exclusively file-based.

Tauon does not behave like this. While it is capable of automatically exporting file-based playlists, they are inherently proxies for the "real thing", as it were. Tauon does not automatically import changes made to these files, nor does it automatically load in new ones. This means that playlists can be synced from my computer to my phone, but not the other way around.

I think the best way to fix this is to be able to set a folder of playlist files within Tauon. Every time you open one of these playlists in Tauon it will read it off the disk - every time you edit, Tauon will write it to the disk. New files that appear in the folder will be automatically imported. This will allow me to properly sync playlists between multiple devices, and therefore to finally create my perfect spotify replacement that I have been hunting now for most of a year.
