Feature Request - Add FTP as a source

[asc11111]

Would it be possible to add an FTP server as a source for photos? I want to be able to give my MagicMirror to my parents and upload new photos to an FTP server so that they get new photos of the grand kids without me having to install them locally.

Parameters would need to include a folder path so that I can have different photos for different MagicMirrors.

This would be possible, but non-trivial, the module would need to act as a proxy between the browser/electron and the ftp server, as browsers don't allow images to be loaded via ftp. I already do this for my MMM-RainViewer module, so it would just be a matter of reusing that bit of code and finding a good ftp client on npm.
