===========================
foreach efficient looping
===========================
Description:
Provides efficient looping through sparse data sets, such as connected
players. Significantly improved from the original version to be a generic
loop system, rather then purely a player loop system. When used for
players this has constant time O(n) for number of connected players (n),
unlike standard player loops which are O(MAX_PLAYERS), regardless of the
actual number of connected players. Even when n is MAX_PLAYERS this is
still faster.

the problem, and I've tried to make sure that the values will never actually
