Feature Request: options to sync/desync an application using CLI

[easypickings]

I find it quite indirect when trying to desync a single synced application.
I have to manually copy back the file(s) and modify the config.
It would be convenient by adding CLI options like mackup sync <application> and mackup desync <application> to automatically get the works done.

I agree this would be helpful. @lra, do you have some time to work on this soon? I might be able try it out in the next quarter.
