Add a sync log
As soon as #13 (closed) is done, we should be able to synchronize a local/remote folder pair. However, for the sake of debugging issues (or also just for information for the user) we should also allow displaying some information about what is done. For this purpose, the DirectorySynchronizer
shall get some kind of API which allows reporting actions that are run including some time stamp as well as informational text.
