Allow title case in Wiki page title

Now we have this:

{page slug, lowercased, but the first letter is uppercased} · last edited by {user} about 2 hours ago

I think, will be nice to use this function of Gollum for generate page title:

Custom titles via CLI If you start Gollum with the --h1-title option, then the first <h1> header on the page will be used. So, for example, this markdown page:

# This is my title
# This is the first h1 that will be displayed

will be rendered with the This is my title page title. The first header rendered in the page's text will be This is the first h1 that will be displayed.

Gollum's wiki

But, sometimes, page does not contained any <h1> header. In this case, I suggest to use the raw page-slug (without any case modification).

Thanks.
