Allow dragging & zooming of canvas #40
Description
We should allow the user to build a diagram as big and as complex as they'd like.
To support this, we should allow the user to drag the canvas around (using middle mouse button) so that they can add nodes in places that would be default be off-screen.
This also acts as a great solution for if nodes end up stuck under the new/save controls, the user can just drag the canvas so they aren't under the controls.
Further, we should also allow the user to zoom the canvas in/out so if they have a large, complex diagram they could view the whole thing on the screen at once.
This should be done with cmd/ctrl + scroll -- we will need to hijack this from the browser's default zoom behaviour when in the diagram editor view.
