v1.6

• Code to add to menu.py more robust, so tabtabtab errors will
  never prevent Nuke from starting
• Search string starting with space will disable the non-consecutive
  searching, so [tab][space]scen will create a Scene instead of
  a highly weight ScanlineRender
• Exposes menu items in nuke.menu("Nuke") along with the nodes.
  Meaning items in the "File" menu etc are exposed, for example
  [tab]exit will be the same as "File > Exit"
