Playlist drag and drop issue on Wine/Linux

[TT-ReBORN]

- Drag and drop music files to Playlist is not working. See reported Wine bug here.
Wait until @TheQwertiest does fix dnd bug since SMP 1.6.0 to apply Wine workaround, see here.
( Drag and drop works in the window if you use Files -> Add files/folder ).
NEW: since Beta 11, drag n drop is fully operational, you need to downgrade and use Spider Monkey Panel v1.5.2:
https://github.com/TheQwertiest/foo_spider_monkey_panel/releases/tag/v1.5.2

The playlist drag and drop issue has been fixed by Wine devs since Wine 8.
There is no more need to downgrade to Spider Monkey Panel v1.5.2, just use the existing SMP in the theme.
