sorry for the last release. It made K3b just sit there and do nothing when attempting to burn a data CD or DVD on-the-fly. This release fixes that and three other things:

* Fixed crash when refreshing the device list.
* Fixed cancellation of adding files to a data project.
* Fixed on-the-fly data project burning.
* Backported a warning about following links to folders (K3b cannot do that after the link has been added to the project).
