Title: Added :center option to oval

The manual says that the oval method can have a `:center` option, which will make `top` and `left` mark the center of the oval. Red Shoes does this, but purple shoes doesn't. Now it does :)

Here's a sample app that should draw a snowman:

```
Shoes.app do
oval(200, 100, 40)
oval(180, 180, 120, 120)
oval(radius: 100, left: 240, top: 400, center: true)
end
```
