King Mode: Fix king placement phase not working correctly with multiple teams in a clan New king placement phase rules: * Before the game begins, each team can walk with their king and teleport for free, everything else is disabled * This special round does not count towards the round counter, like in gfPlaceHog * TotalRounds is set to -1 during this round, like in gfPlaceHog Under the old rules, this was much more hacky. The delay of all delay-less weapons was just set to 1 The problem with the old rules was that if any clan had more than 1 team, eventually the weapon delay will time out before all kings have been placed.
