Fixes FS#204: Observe all used directories

- Implementing the FileObserver in a separate class, with mask to watch only deletions not everything
- Add observation of all directories which could contain a sent/received file
- Change observers if the folder names are changed via settings
- markMessage method moved from XmppConnectionService to MessageUtil
