* Replaced right-click search textbox in schematic and tree views with a menu built-in combo box
* The search combo box is auto-focused on right click and goes away if escape is pressed
* The search combo box allows selecting with arrow keys and creates the selected object in view on enter key

+ Tree view filter icons and search box are now in a separate menu bar (consistent with schematic view)
* View menu bars are now more compact
* Tree view bone filter now works
