HTML5 fragments inside markdown content emits warnings for elements without body

[gpakosz]

Currently, the html parser expects XHTML content and will warn about non-self closing tags without body. E.g. <img> and <br> tags.

if !closed && HTML_ELEMENTS_WITHOUT_BODY.include?(el.value)
  warning("The HTML tag '#{el.value}' on line #{line} cannot have any content - auto-closing it")
  closed = true
end

in lib/kramdown/parser/html.rb:89

Could we get rid of or have an option to disable that specific warning? I guess nowadays more and more people expect to be able to have fragments of HTML5 inside their markdown documents.

Thanks!

Okay, I have removed the warning messages altogether.
