Corrected namespace of doctype handlers
Added toolbar disabled styles
Fixed toolbar bugs

Prevented creating new menu items when refreshing the tree. Made sure
that on selecting a node only the toolbar for the corresponding tree is
used when checking the disabled attribute.
Moved position of toolbar context menu...

… to above the menu bar. (Leave more precise positioning to CSS
margins? - may need extra class to do this...)

Added a timeout delay for the marker hover, so that it only appears
when the user waits a moment. Prevented duplicate markers on the page.
Removed deprecated code. Fixed bugs with flickering, and displaying in
Firefox (now hidden on document.mousemove rather than mouseleave).
