v2.9 released

Multiple small adjustments and bug fixes. Most changes are listed below. **minimal spoilers**

Added zone around certain bosses to play music and slow down the player. This is intended to let people know if they are near the boss (in case they still want to collect the history item). Maps without any history items do not have this feature.

Those zones created a rare bug I can't seem to fix, so I added an ADMIN RESET item in the player inventory to turn off music if still playing after leaving a map.

Graphic bug fix on dead bodies when speaking at them early in game.

Added dialogue when trying to enter buildings while in the area with dead bodies.

Small sequence change regarding the point where your "partner" character is missing. Talk to the aliens first.

Bug fix on the transit tube system. Player will now retreat instead of sometimes moving forward (when cancelling travel).
