#593 scripts in svg project files don't work

[Lee Worden]

SVG is similar to HTML, and SVG image files can contain script tags. To support them, it would probably be necessary to either translate the src url from relative to absolute, or to embed the SVG in an iframe and use the same GetProjectFile URL trick that I use with HTML files.

Unlike HTML however, SVG needs to come with a way to fall back to .png image for browsers that don't do SVG, so I have to make sure that's working as well, whichever way I go.
