Add toggle to match inline title color to H1 color

fixes #264

i feel that is a little but great addition, avoiding people headaches to deal with css snippets

Forgive me for asking, but wouldn't applying every h1 customization to inline title make more sense? I can't see any reason not to add other values as well, unless there's a reason not to.

mmh that's actually a good point, I think I'll check out what other popular themes are doing so we can have an idea of what users are expecting

I think it should be a separate setting. It could go above the H1 dropdown and would have the same settings as each header (font family, size, weight, height, color and maybe even an option for a divider)

Anyways, this is a really nice addition!
