Add site options for _site.yml and navbars for R Markdown websites

R Markdown has a simple website builder baked in (see the R Markdown book for a detailed description). An R Markdown website must have at least have an index.Rmd file and a _site.yml file (which can be empty). Including YAML in _site.yml will apply it to all R Markdown files for the website, e.g. setting the output format here will tell R Markdown to use that format across the website. R Markdown websites also support navbars, which you can specify with YAML (see yml_navbar(), as well as ?rmarkdown::render_site and ?rmarkdown::html_document). Pass navbar_page() to the left or right field to set up page tabs and use navbar_separator() to include a separators. In addition to writing YAML with yml_*() functions, use_site_yml() will take the a yml object and write it to a _site.yml file for you.

yml_site_opts(
  .yml,
  name = yml_blank(),
  favicon = yml_blank(),
  output_dir = yml_blank(),
  include = yml_blank(),
  exclude = yml_blank(),
  new_session = yml_blank(),
  ...
)

yml_navbar(
  .yml,
  title = yml_blank(),
  type = yml_blank(),
  left = yml_blank(),
  right = yml_blank(),
  ...
)

navbar_page(
  text = yml_blank(),
  href = yml_blank(),
  icon = yml_blank(),
  menu = yml_blank(),
  ...
)

navbar_separator()
