- Dialogs defined in UI files had two different places where a default size is defined (in UI file and code). Removed definition from code and adpated UI files.
- The default size of the options dialog is too small to accomodate the content. Actually the .ui file was once set to a sensible default, this is used again now.
When an error occurs during loading of a release, it will be visible
in info dialog for this release (which was unused).
New icon was added to mark visually releases with errors, and scrollbars
will appear in info dialog if needed.
