Make first-heading-level configurable

[michaelmior]

It would be nice if an option could be provided to the first-heading-level rule to set it to something other than 1. I have a case where all my Markdown files should start at level 2 instead.

What's the case?

[michaelmior]

I have a series of Markdown files which represent articles. The article title is in the metadata and gets rendered into the top-level heading in a separate section of the template from the content. The article content should only contain headings starting at the second level.

[wooorm]

OK, I’ll accept a PR for this!

[michaelmior]

This looks pretty straightforward save for one caveat. This has an obvious interaction with the no-multiple-toplevel-headings rule. Is there currently any way to share settings between rules? If not, is it reasonable to just make this option required for both rules and leave it to the user to set them to the same value?

[wooorm]

No, there’s no way to do that. I think it’s reasonable to to leave it up to the user!

[michaelmior]

Updated both rules to allow specification of the heading level.

👍 merging!

[wooorm]

I’ll release this once travis completes.

Released in 3.1.0!

Awesome! Thanks :)
