Script Event Page Conditions

#Script Event Page Conditions v1.1
#----------#
#Features: Set conditions for event pages to activate via script calls made with
#           comments. Comment must start with SC: and be the first thing listed
#           on the event page. Note, that's "SC: " with a space and not "SC:".
#
#Usage:   Comment:
#           SC: script_call
#
#         Example:
#
#           SC: if $game_party.gold >= 100
#
#          ^^ (that page will only activate if players gold is 100 or higher)
#
#           SC: unless $game_party.item_number($data_items[0]) <= 2
#
#          ^^ (that page will only activate if player has less then 3 of item 1)
