Warpinator: Add symbolic link support

[ghost]

Just an idea. Add symbolic link support. I work with alot of media, and how I sort my medias into folders are done via symlinks (I make those files act like as if I favorited the files, but in a bulk, that starring couldn't achieve), and when I'm trying to send a folder full with symlinked files, it just fails with symlinks not supported error message.

KDE's dolphin has this built in, and works like a charm, by rsync as the backend.
