You can do this by extracting the pk3 file that hosts the map, finding the scipt file (should be in the maps folder, file extention is .scr) then edit the line that looks something like this:

DM_respawning=1

Or something similar to that (been months since I edited a script and I'm at work now). Once you've done that save it and re-compact the files into the pk3.

That should allow respawns.

If you want a complete step-by-step walk-through on how to do the above I'll do it later on when I get home, if you like. You can edit all sorts of stuff using this method.
