@onizet FYI. This PR breaks any Word documents where you are using standard headings. I noticed that when I switched from the latest NuGet package to the code on the dev branch all my headings were using the default styles.

By default, Word uses styleId="Heading1" and name="heading 1" for the header style. All header paragraphs will therefore reference "Heading1". The code in this PR updates the styleId of every Heading {n} style to the name, which breaks the link from the heading paragraph to the style.
