Scroll bars

I wish the canvas had scroll bars. It's easy to get disoriented without them.

I'd previously filed issue #50 thinking that it was caused by missing scroll bars, but I realized that scroll bars are a separate issue, so I filed this one. This comment from @jeremydouglass is relevant to scroll bars:

Twine uses scrollbars like this. It also restricts the user to a small number of preset zoom levels, rather than offering free zoom (which may be disorienting for beginners).

Another option instead of direct scrollbars is a dragging hand tool, however this is often paired with a HUD box that shows where the current view is on the total canvas, and that can get complicated really quickly.
