PDI-9448 Removed dependency on obsolete kettle-db jar
PRD-4426: Display crosstab only in experimental mode and not expert mode
PRD-4443: Fixing invalid event handling for query-attribute changes.

Also: Refactored report-tree to split it into a layout-tree and a data-tree. The class was trying to be both kinds, which is bad design. Duplicate code is now in AbstractReportTree.
PRD-3343: Event handling for adding or removing parameter or expressions made more specific. This allows the JTree to preserve its selections and state.
