tags.lisp: Added SVG tags to *html5-elements*

[nerap528]

Spinneret screams at me when I work with SVG files.
I also added every SVG element listed here https://developer.mozilla.org/en-US/docs/Web/SVG/Element, so it will be happy forever.

[ruricolist]

Could you fix the whitespace change to *html3-elements*?

Also, I'm curious, how well does this actually work? I was under the impression embedded SVG had to use XML syntax, which is not exactly what Spinneret produces. Are there any issues with SVG attributes?

[nerap528]

The added whitespace at *html3-elements* has been removed.
Here is an example of how the svg elements are used. (The relevant codepen: https://codepen.io/alvarotrigo/pen/RwLGjKq)

The output spinneret generates is rendered exactly as shown in the codepen.

Apparently tags from the math and svg namespace don't have to be self-closing, so the output generated by spinneret is totally fine. Neither Firefox nor Chromium complain.
Foreign elements must either have a start tag and an end tag, or a start tag that is marked as self-closing, in which case they must not have an end tag.
