Syncing support

[mikedougherty]

Synced prefs and accounts have long been a feature of digsby, but now that the first-party implementation is being removed, there should be a plugin to re-enable this functionality using (a) third-party service(s).

Possibilities include Box.com, Dropbox.com, drive.google.com, and several others. At least one of these has a reasonable python interface, so adding support shouldn't be too difficult.

After I installed, I copy and pasted the folder into Dropbox, and have had zero issue so far :)
