* 'wip/wxgui' of http://gnuradio.org/git/jblum:
  using gr copy in the wxgui connect, added gr copy to grc xml
  Added gr.copy(itemsize) block
  point label transpareny, horizontal offset, and toggle on/off capability
  simplify some params
  moved the wxgui connect helper functions into the wrapper class
  making use of update ui event
  setup special wxgui connect on sinks, needs testing
  working special connect for fftsink
