Subject: [PATCH] Handling multiple base dirs, closes #114

- not very cool solved, but when files are not
  in current base dir for project they will
  be rendered just as done formerly. Means
  of course that maybe images are not correctly
  shown, but at least content is there.

  Also users got the possiblity to close all
  editors  open file and do refresh - this will
  reset the base directory
