[FEATURE] Edit synchronized folder item

[MarkusH604]

I sometimes need to adjust the login details, e.g. the host name. I started with an IP, now want to go for a dyndns host name. As a user, I'd like to double click on the item in "synchronized directories" and receive the same dialog as if I were to create a new item. Instead of a blank dialog, I'd like to see the specifics of the already defined directory and use that to adjust the defined item. As an alternative, I delete the synchronized folder and start from scratch.
