Diavolo I improved a lot code completion in this 0.61, it's almost ready...

  • completion popup not shown any more when the user moves the caret from one token to another using arrow keys or the mouse pointer
  • control-space key combination opens the completion popup if it can
  • fixed two bugs when the token value the completion popup depends on is unrecognized
  • changed the completion grammar to allow values that are available for all suggestion groups
  • started optimizing the code
