Widgets in pkgdown sites

htmlwidgets in pkgdown sites need special treatment for some site components.

• If you include widgets in a README.Rmd, add always_allow_html: yes to the YAML front matter. You’ll get a error if you try to knit the document without that option.

• If you include widgets in your vignettes, use chunk option out.width = '100%' to ensure the widget spans the entire container.
