EaselJS: Animation 2 (Pausing)

So apparently, you can tell Tick to pause, and it just keeps on going... But it will tell any animation that cares to know, that they should pause if they wish. Seems a bit odd, but maybe it will make sense later.

9) Adds a button below the canvas that will tell the Ticker it should/should not be paused.
5) The function that does the pausing/unpausing.
6) A variable that sets itself to be the opposite of Ticker's paused status.
7) Changes Ticker's paused status.
8) Changes the text on the button to say pause/unpause, accordingly.
1) Animates the normal circle.
2) Checks the pause status of the Ticker
3) Animates the pauseable circle, but only if the Ticker is not paused
4) Updates the image on the canvas - needs to be outside of the pausable code, or normal circle will keep going round, but you won't see it happening.
