Revert change to SE_LimitEffect

Also fix for SE_SummonItem for unstackable charged items
(Still need to verify on live though)
Improve feign_memory_list thanks to C++11
Reversed event_command return value, may cause visual issues if you already updated your code but easy to fix.  Return 1 instead of return 0 on event_command dispatch
