Change cursor while mouse hovering text-buttons or dragging panels
Most programs change the mouse cursor to a text-cursor if the mouse hovers a text field to give proper feedback. Blender didn't do this, so far. The same applies to drag & drop events. The cursor should turn to a hand-cursor in this case.
This patch changes the cursor to a text-cursor if the mouse hovers a text button and to a hand cursor if a panel is being dragged.
