Added Workshop Tags

Fixes:
Autosave fix (Office fight), music fix (Train station fight), AI-bugfix on one enemy

Changes:
difficulty increase, ammo was sightly reduced

Note:
I'm sorry for the issues the map had until this point. I'm sick right now so I relied completely on skummeh's gameplay and feedback. The ammo balancing will be better in the future when I'm able to test everything again.

Train Station Music fix and other small fixes and changes

Fixes:
AI improvements (in the train station, sewers, and office), AI bugfix on a Zombie, fix for the music at the end, minor performance improvements,

Changes:
change of the music at the train station, apartment at the start made more believable (ammo isn't scattered in drawers o the fridge anymore its all in the first room)
