Inyoka Markup: `[[Anchor(NA">ME)]]` creates exotic HTML-ID

[chris34]

For an example see

inyoka/tests/apps/markup/test_html_renderer.py

Lines 252 to 256 in 48cf8d5

	html = render('[[Anchor(NA">ME)]]')
	self.assertHTMLEqual(
	html,
	"""<a class="crosslink anchor" href='#NA"&gt;ME' id='NA"&gt;ME'>⚓︎</a>"""
	)

For JS/CSS if we we want to access them, it is needed to escape it
document.querySelectorAll('#' + CSS.escape('NA">ME'))

This can be at least non-obvious.
(As far as i see it, no HTML can be injected though)

If not all characters should be allowed in the future, the question is, if existing links get broken?
