[qrvthtool] Set KAboutData.

TODO:
- Use KCrash, but it shows bugs.kde.org as the bug reporting address...
- KIO writes to qrvthtoolrc in ~/.config/, and it doesn't seem like
  there's any way to easily fix this, since KIO uses the default
  path (QStandardPaths::GenericConfigLocation) for KSharedConfig.
