Stop the endless loop

Awesome new version [0.9-alpha] 😃 😃 😃

• Added a stop button that can stop the execution of current script. 👍
• 10 millisecond pauses for prints and other statements. (Prevent app crashes) 👍
• Download is smaller now.

I'm going to use this for my tutorial series at http://pandabunnytech.com 😋
