Requires double newline after header

[ralfstx]

I have markdown files that look like:

---
---
# Header
Bla bla ...

This markdown is rendered by GitHub as expected, an extra linebreak after the header is not required. However, the title is only extracted if the header is followed by two newlines.

Thanks @ralfstx! Would you be interested in submitting a pull request to implement this?

@benbalter I'm sorry, but I don't have a ruby background and I'm lacking the knowledge and the tools to build and test a change.

My guess is that either the trailing \n or the $ needs to be removed from the regex in https://github.com/benbalter/jekyll-titles-from-headings/blob/master/lib/jekyll-titles-from-headings/generator.rb#L5
