Bugfix 1.0.1

A very quick fix to some bugs I overlooked when I initially uploaded the game:

• game no longer freezes when exiting to the main menu
• game screen maintains consistency when the window size is changed
• stats now appear in the stat screen
• a stamina bar was added to the inventory to keep track of how much you recovered
• itens now show how much stamina they recover
• changed nuggets and burger stamina recover and price
