New version number, synched to upgraded GVRET version. Some fixes to make file comparator window work better. Add ability to enter single wire mode from SavvyCAN. Add continuous comm validation to SavvyCAN. It will now continuously make sure the connection seems to be viable and try to reconnect if things went south.
