Feature request: use == for highlighted text

[lduperval]

Hi,

I'm not sure if this is now commonly accepted syntax, but it would be great if you could add the == fences to import/export.

I often use this to highlight important information in my documents and it gets "lost in translation" now.

We can detect highlighted text (or at least text that has some background color) in a Google Doc, but not all Markdown renderers recognize the ==highlighted text== syntax. We can add <mark>highlights</mark> though. Github Markdown does not recognize either of those but at least the HTML markup doesn't appear literally (except here where I used the character codes).

What are you using to render/view your Markdown? Stackedit does render both the == and the mark (HTML) markup for highlighted text.

I'm inclined to add <mark>highlight</mark> as it fails gracefully if not supported by the Markdown renderer.
