Changelog 1.1

- Removed some unused files 

 - Fixed a bug where you hold multiple tools 

 - Changed some settings for performance and hopefully reduces dedicated memory for GPU usage. 

 - Added a new button to the main menu to open another level for the "cavesystem". THIS IS A PROOF OF CONCEPT. meaning it currently has no use or assets, just walls and floor.  Everytime the level is opened a new layout of the "cave" is generated.
