Jacques Lucke 1e23f9235c Nodes: highlight frame that nodes will be attached to
Previously, it was somewhat difficult to know if a dragged node will be attached
to a frame or not. This patch highlights the frame that dragged nodes will be
attached to which removes the guesswork. This is similar to how we highlight the
link that a dragged node will be inserted onto.
