Merge dev Feature additions

* Allow for curly brackets on the same line as if statements and while loops (you need a space between the argument and bracket ex. `if 1 == 1 {`)
* Scaling sprites
* Different window scaling options, provided as an extra argument in ZS.Graphics.Init `ZS.Graphics.Init("Title of window", screenWidth, screenHeight, scalingAmount)`
* You can now use `include` to use the functions and variables from another Z# file inside of your script. use like so: `include "./path/to/script.zs"`
