TODO list:

for 0.6.x/0.7.x:
- Add option to hide/show hidden items in the preview dialog.
- Executing an entry in the search dialog will add it to the browse list
- Add tooltips to show info about shares.
- Smb4K should rescan the workgroup/host, when a "+" has been reopened again.
  Put this also in the pop-up menu.
- Add per host port definition.
- Add per share filesystem definition.

Later:
- Redesign the main window:
  * Remove tab widget.
  * Introduce tooltips for share items.
  * Introduce tooltips for network items.
  * Put the search dialog into popup dialog.
    (Maybe we can also leave it in the main window? -> Redesign!)
- Add scan of IP address range to look-up methods.
- Add drag'n'drop support to the Smb4KShareWidget.
- The functions of the mounter should only take Smb4KShare objects.
- Definition of file system per share.
- Add support for synchronization. Both directions should be supported:
  - local copy -> share
  - share -> local copy
- Is there any function in the C library/the system libraries that provides a list
  of all (non-system) UIDs and GIDs?
- Add support of multiple WINS servers (How?).
- Smb4KPreviewDialog: status bar with item/folder number; add 'back' button
  (therefore allow multiple entries of one path).
- Check intervall for the import of shares can be configured by the user.
- If you change via TAB into a list view, the first item should be highlighted.
- Smb4KScanner:
  + Add automatic, periodic scanning of the network. Make it configurable.
- Smb4KBrowserWidget:
  + Popup menu
    * Send Message
    * Expand
    * Collapse
  + Expand and collapse functions.

To be decided:
- Add ability to browse with VNC viewer.
