[8.73] beacon teleporting

[GEN_Schwarzkopf]

@toyboatt: It's unlikely, that the problem has to do with specfic players. But a replay would be really helpful for finding the problem.

@stachus: That's the way it's supposed to work. The cooldown, introduced in 8.73b, prevents multiple players from teleporting to the same Beacon at the same time. Only the first one gets there, the second player has to wait for the 4 seconds until he is able to teleport.

This new "feature" is not well known and has caused alot of flaming. The change is so significant it almost needs to be on the loading screen so people know about it.
