Changed implementation to use maps instead of lists to find tree items and meta items. This is probably much better performance wise, and the code gets much cleaner.
Changed the background highlight code to highlight all tree nodes that aren't TopTreeItem:s to enable category items to be highlighted.
Cleaned up some code.
number of QTimer instances and the number of redraws to hopefully
increase performance.
Changed so that when a child gets hilighted it will hilight its parent.
This will allow us to build a parent project for
qt-creator that sits above both openpilotgcs and
uavobjgenerator so that we can build both projects
at the same time.
