- Implemented visitor support to KonqFrameBase and children, to reduce interdependencies,
  moved printFrameInfo to visitor, and used visitor in unit tests too, to inspect structure.
 - Simplify KonqMainWindow ctor
 - Pass explicit mimetype to addTab() (fixed one performance bug, in kde3 branch as well)
 - Simplify splitView arguments
 - Unit tests for most of the KonqViewMgr API, to allow for further refactorings
