v0.11.3 is now out

This is the first real 0.11 bugfix release. It is highly recommended to update.
The VideoDVD project does not work at all in K3b 0.11 and 0.11.1.
Here is a list of the fixes:
- Fixed the VideoDVD project. It was not sufficient to use the -dvd-video parameter with mkisofs.
- K3bProcess now has a clean API and a non-stupid implementation which fixes the KDE 3.2 issue way better than the hotfix from 0.11.1.
- Added read retries and ignore read error options to the DVD copy dialog.
- Add files to a project by dropping them on the corresponding tab.
- Removed the query cddb option from the copy dialog since this is configured globally anyway.
- Fixed media detection problems with Plextor DVD writers.
- Fixed some on-the-fly DVD copy problems.
