Option to have remark-abbr substitute definition for first occurrence.

[roxspring]

In written documents, it's common for the first occurrence of an abbreviation to be introduced with the definition first followed by the abbreviation in brackets. It would be great if the remark-abbr plugin could optionally do this. e.g.

This plugin works on MDAST.

More stuff about MDAST.

*[MDAST]: Markdown Abstract Syntax Tree

Would translate to:

<p>This plugin works on Markdown Abstract Syntax Tree (MDAST).</p>

<p>More stuff about <abbr title="Markdown Abstract Syntax Tree">MDAST</abbr>.</p>

This would be especially great for workflows where documents are being composed of multiple markdown files and it's not immediately obvious which file will be introducing a given abbreviation first.

@roxspring I like this idea. Would you be interested in implementing it?

[roxspring]

Sure. Will aim to give it a try soon.

Is it ok here?
