Humans: Milestone v1.1 released, major improvements.

Some days ago I decided to improve this game a little bit and also fix some bugs. The result was a v1.1 that looks way better than the previous one.

Those are the changes this update brings:

•  New PBRs for walls, grounds and objects.
• New models for several objects.
• Several materials were improved.
• Lighting was improved.
• Several physics collision boxes were fixed, in the older version, tunneling could happen and some objects could go through other solid objects.
• Monster sight was fixed, it had a bug that was making him blind sometimes.
• A bug where the monster could get stuck was also fixed.
• Monster behavior was also improved.
• Final and last one, a new puzzle was added.

Hope you guys enjoy the changes.
