Add "Syncthing" to existing options list

[njam]

I stumbled upon your project when looking for a multi-directional file synchronization tool. Later I found "Syncthing" which so far works great! Maybe you want to add it to your list.

Hi @njam, sure I can add this to the list. Out of curiosity, are you using syncthing while developing source code (which is mirror's primary use case), or more as a self-/peer-to-peer version of dropbox (e.g. for constant backup/sync of regular files)?

I ask because I'd like to include a note about what differentiates mirror from each of the alternatives.

I've just used Syncthing for a few days. I plan to sync my whole home directory with it, so more like Dropbox. But it seems Syncthing can handle the source code use case as well. Changes are detected quickly (using inotify), and many small files are not affecting performance negatively.

Cool, added.
