Catch Monika in the Act / NSFW Door Greeting

[TreeWizard96]

# CATCH MONIKA IN THE ACT
# This is a sequence heavily taken from the event where you open MAS to a black screen and\
# need to open the door, knock, or listen
# There are a few different ways this can play out.
# For our purposes;
# 1. The player can listen in on Monika 'in the act', once per run.
# 2. The player can knock, interrupting her, but getting a positive response.
# 3. The player can open the door. The response changes based on if you knocked first.

Before adding this to the game:

• Assign non-placeholder poses to all dialogue.
• Do more testing of the implementation - I have already done testing using the console, but need to see if this greeting shows up organically too
