Table of Contents with the NovelWriter HTML format

[AlanDunaway]

Reference issue #1545

How can we create a table of contents in the HTML file NovelWriter exports? For example, I'd like to have tags in chapters, when I click the link in the ToC, it would jump to the chapter I want.
Like:

#! Book title
Author
Table of contents
Chapter 1(link)
Chapter 2(link)
...
Chapter 1(jump to this if user clicks the link)

I've just added code to the build tool to generate an outline of the manuscript, which will be displayed on the Manuscript Build tool dialog. This generated outline can also be used for this purpose, so it's a step closer. See #1765 and #1768.

The question now is how to know where to insert it in the manuscript. I guess it would make sense to add a [TOC] in the text where it is to be inserted.
