Red Tonya update

From the players perspective not a lot has changed.  I have streamlined the code to be more editor friendly when porting data from LDtk including a major rework to the json file system to handle items like entities, tile placement, object properties etc, which means there is less for me to do when porting between the level editor and the code. 

Also I have included in this version a bat which is also editable from the LDtk which will interact with the character ready for the health  system. 

If you find a bug please let me know and of course suggestions are always warmly welcomed.
