Images on page

Now that we have easy canvas rendering, we should have a "Save as PNG" button. Would also make doing fun stuff with hashblots easier.

One idea I have for this: make a "Render PNG" button that replaces the SVG with the equivalent PNG. Users can then right-click -> save as or whatever.

Another approach: have a server that generates PNGs. This way, the images can be hotlinked to Imgur, thumbnailed on Reddit, etc.
