add .inner_html() builder method

[alsuren]

This is useful for injecting SVGs into the dom.

I have not tested this with SSR or hydration, because I'm not using them in my current project.

I guess this relates to #288 - we have tried a few things in 0.7-land, like:

• building svgs by hand using the builder api (typically a bad idea, because you end up with an svg that it impossible to view or edit outside of rust-land)

• falling back to the view!{} macro (okay, but typically forces you to add another layer of div or span that you don't really want).

• encoding the svg as a data url:

  let icon = format!(
  "data:image/svg+xml;charset=UTF-8,{}",
  utf8_percent_encode(source.icon(), ASCII_SET)
  );
  img().attr("src", icon).build()

Since this patch is tiny, we might backport it to 0.7 as well, so I can see how it feels when used with our existing codebase. That way, we give an experience report.

Is it just the function name change that is blocking this from being merged? :)

Sorry haven't taken a look in this in a while. It's that and also I'd like to keep the example the way it is right now to be consistent with the non-builder equivalent. I can push a commit on my side to fix that and merge this soon.
