Removing HDR

• Removing almost all textures to see the wall better
• Removing props
• Removing some bugged textures
• Removing the Dynamic Light system
• Adjusting the cart path
• Replace some world cube to brush entity
• Removing the Light HDR

I removed everything that are useless for the Alpha version for now, i'll try to rework it. If someone is interested by working on this map too, you're welcomed !

Since the map has been tested into TF2M Test server, i got a huge amount of feedback.

• RED Basement is too dark
• Avoid using animated character
• Avoid too much phys_props
• Cart stuck to A door

So, I'll consider that feedback and try to correctly rework the map to make it playable !

Since i can't test the map because of the HDR, i removed it.

well i needed this for some reason, so i added it
