Ditched points system for cumulative time system

Working out each player's points every time someone sets a new PB turned
out to be too much work for the server. Instead people are now ranked
overall by their total (cumulative) time. If they haven't set a time on
all the maps, a high time (controlled by zr_maxtime in tics, e.g. 1050
which is 30 seconds for CTF) is set for each map a player has not
completed. zr_totalmaps must be set to the amount of maps on the server
so that this can be worked out properly. When transitioning from the old
points system version to this new cumulative time system, the admin must
puke script 469 to convert the database. If new maps are added, Zanrun
should add zr_maxtime*number of new maps to each player's total time
(assuming you also update zr_totalmaps), however you may want to puke
script 469 again just to be sure.

Fixed bug - players could teleport when dead causing voodoo dolls.
Fixed bug - personal TP binds now call the scripts as execute always to
allow people to teleport at the same time.
