Fixed a vent that would leave the Reaper stuck in the ceiling when exited.

• Fixed the crashing, hopefully, through various tweaks to the scripting. Have fun using any primary weapon you like!
  
• Added a vent to prevent players from getting stuck if the Technician plants mines in the last stage.
  
• Reworked dialogue. You now have to view the cutscenes before being able to progress, to prevent a specific crash.
  
• There isn't a shotgun blast at the start of the level anymore.
