Create Options

This resets all the canvas bindings to the default values. These are :
- Select New Object.
- Deselect Current Object.
- Move Selected Object.
- Scale Selected Object.

This option was added to stop the user getting stuck in any one mode. If a
radiobutton function is selected, but is not required, pressing the Default
button returns from the function bindings to the default bindings.
