Group front-matter variables in templates

Breaking configuration change. If you use custom templates, please update them:

Front matter variables in templates must be preceeded with `fm.`, e.g.
`fm_author` becomes `fm.fm_author`, `fm_title` becomes `fm.fm_title`,
`fm_subtitle` becomes `fm.fm_subtitle` and so on.
