Sync all the directory tree

[jlausuch]

It would be nice to have recursive sync for a specific directory. When working on projects with multiple directories, it's a pain to configure an entry for each one of them. Something like this:

{
     "enable": true,
     "localPath": "path/to/dir1/*",
     "remoteHost": "remoteHost",
     "remotePath": "remotePath"
 }
