Burtle

1. Fixed file that was breaking the event decorator

1. Instead of doing a while loop, then running the mainloop() function inside of it, you can now simply use the run() function without any other loop
2. To add logic or anything else you'd do in the while loop, simply make a function with the "event" decorator, it will be ran automatically when calling the run function at the bottom

1. **solid** argument (bool) can be passed on creation of a burtle, this will not allow other burtles to move through it if you are using the default_keys method for movement

fixed versioning 😳

messed up the version number!!

Added arrow keys to event listener, under the names: "up, down, left, right"
Removed more debug print statements
