* 'master' of github.com:thehogfather/pvsio-web:
  diagram animation is now disables (was buggy, needs further development)
  force layout animation used to position nodes when creating a new diagram
  Fixed bug in function init()
  fixed GPCA-UI demo (the new version of function startPVSProcess requires a structure with fileName and demoName); added sanity check in pvsWSClient to catch situations where fileName or demoName are undefined (and therefore the demo cannot be started)
  Update README.md
  fixed selection bug in ListView (the editor was not updated with the selected items); changed rendering of selected files (now using steelblue as background, and half triangle to indicate clearly which item is selected)
  Now user can create a diagram using a specification and modify the specification using the diagram itself
  alarisGP now specified with multiple files; removed print margin in the editor (not needed for now)
fixed bug where file list items are marked dirty whenever the selection from the list changes
