* Fixed 'sticky hierarchy' option giving error
* Fixed 'minimize wire distances' option not working and giving exception in schematic views

* Double clicking on a scene node in schematic just selects itself (without the node's full hierarchy), treeview behaviour is the same
* 'Hierarchy' toggle in tree view objects mode is moved from objects item to the top toolbar to allow toggling even when objects item is not in view
* When in 'flat' mode none of the items have expand/collapse buttons

* Improved tree views's always show selected behaviour: 1. the view now scrolls so that selected node visible 1'rd of the view from its top, if multiple

2. If multiple nodes are selected the view will scroll such that the whole selection is centered 1/3'rd from the top
3. If the whole selection doesn't fit inside the view it is scrolled such that the top of the selection appears right below the filter bar (if it is visible)
* In multiple pane configuration tree view now displays nodes below and above the filter bar (not underneath it)

* RenderStates -> StateSets, more work done one StateSets although still no GUI
