Fix bug loading CUP waypoints, incorrect removing trailing quotes.
Bug found by Berthold Bredenbeck after..4 years it was there.
If the waypoint was
"fullname",codename,....
all was correct, name=fullname
if the line is
fullname,codename,..   without quotes "", then name=fullnam  without trailing letter "e".
