Big Push Events for PSDK 2020-07-28

#===============================================================================
# Big Push Events - By Vendily, Converted to PSDK by Nuri Yuri
#===============================================================================
# This script allows you to tether multiple events together to move as one.
# Think strength rocks from gen 5, that size. Or bigger, or wide and thin rocks.
#===============================================================================
# Each event in the unit must contain the same script call:
#   push_many_events(width, height, *list of event id to push)
# Mind, if you're using tiles from the Tileset and Player Touch, the tiles can't
#  have Passage (4 dir) set. It's all or nothing for Player Touch
#===============================================================================
