add a global map to save player parameter

add a global map configuration to save player parameter. it is in order
to resolve a problem that: can not share Mark between "on_trigger" skill
and  "residue_func" skill  in lua code. below is my example:

--[[
一个无法实现的技能：
回合开始钱选择是否发动，若发动，则无限出杀，
我在on_trigger中设置的setMark在residue_func中无法getMark到，所以我实现的这个技能没法工作。
调试c++代码后发现on_trigger和residue_func中的该player虽然都表示同一个玩家，但是其this指针是不一样的，也就是存在两个player实例。所以mark无法共享 。
于是我只能增加一个全局变量来解决这个问题。
你看下是否有这个情况，有这个情况的话可以考虑合并之。
