Hints in the node graph

[0HyperCube]

When in the node graph view currently, the hints (shown at the very bottom of the screen) are just the same as the tool that is selected. This should be changed to node graph specific hints e.g.

• Lmb to select node (Ctrl or Shift to multi-select or Alt to preview).
• Ctrl + H toggle hidden
• Ctrl + D duplicate
• Ctrl + C copy
• Ctrl + V paste
• Alt + L toggle layer
• Drag to move node (shift to drag row)
• Double click enter nested network
• Delete remove node (Ctrl for no reconnect)
