>> Call event from other map by call script:
  
callev(event id, page you want, map ID)
------------------------------------------------------------------------
e.g. callev(5,2,1)
^ to call event commands list from 'page 2' of 'event ID 5' in Map ID '1'
------------------------------------------------------------------------
>> Call event in current map by call script:
  
callev(event id, page you want)
------------------------------------------------------------------------
>> If you want to call event in current page that it's running,
set 'page you want' to 0
------------------------------------------------------------------------
*Note: You CANNOT call erased event!
