Download options for SVG UML

[ExarcaFidalgo]

At least, two download options are to be implemented for the generated diagram:

• SVG.
• PNG.

(Unless it is an exclusive responsibility of the project which makes use of it; it is a possibility. If we can ease such task, though...)

SVG Download is now easy to implementate thanks to the new method base64SVG( ), which encodes the SVG in base64 format. Thus, a download link can be created setting its href attribute with such value, as well as a download attribute.

I gave PNG a couple tries, using whatever examples i could found, but it keeps giving me an empty image. Since there is at least one download option, its priority its low. I'll keep it open, though.
