The last update

This is the last update for the engine made by me.

I passed the development to another person and will put a link to them later.

For now, here is the change list:

• New script command for saving and loading game
• Fixed culling with doors on higher floors
• Scripts binded to keys will not freeze the game now if used fast. However it's a crutch and it will just deny any key binded to scripts for a second after execution
• Fixed some problems with textures tiling
• Fixed textures UV on doors
• Fixed crashing in settings if menu music wasn't added
• Refactored saves system. Old saved games are not compatible!
• Added ability to disable entity culling. It's really the last thing you should use and it will probably not work in some cases.
• Fixed camera tilting setting
• Player hurt script now deals fixed amount of damage
• Fixed static models merging
