B Dup's apartament v 2.0

The second version of the mod that opens Dup's apartment B.
Changes in the second version:
* Now a tuned Camper will stand near the house.
* The exit from the apartment is now through the door (in the first version, the exit was using the keys).
* Now there will be a save pickup in the apartment, and you can save there.
Plans for the third (final version):
* Make a high-quality collision (so that the player does not fail anywhere)
* Make big yellow markers.
* Add B Dup himself and a big bear (as one of the minor characters is called) to the apartment.
Have a good game!
