Fix No Death Mode results being reset before being shown

This does the same thing as the last commit, but for No Death Mode
instead of Time Trials. Whenever you die in No Death Mode, or complete
it, all the relevant variables get copied to variables prefixed with
'ndmresult' that never get reset by script.hardreset(), and these
variables are what titlerender() use, instead of the "live" ones.
