version 1.1 export to gif

You can finally export to gif!!!  I used a great GitHub repository with al the code i needed and even a tutorial on how to use it. https://github.com/antimatter15/jsgif i would highly recommend it if you ever need to convert canvas images to a gif. I also replaced the text on most of the buttons with icons and the last change i made is that the program automatically moves in to move mode when a new stickman is created.
