Data model node - Fixed pins disconnecting after restart

Data model event node - Fixed pins disconnecting after restart
Node editor - Fixed connecting already connected input pins to an output pin causing a crash
Node editor - Added auto-save every 2 minutes while nodes are open (profiles are already auto-saved whenever you make a change, nodes will get the same treatment later)
