Prepend/append extra HTML content to a widget

Use these functions to attach extra HTML content (primarily JavaScript and/or CSS styles) to a widget, for rendering in standalone mode (i.e. printing at the R console) or in a knitr document. These functions are NOT supported when running in a Shiny widget rendering function, and will result in a warning if used in that context. Multiple calls are allowed, and later calls do not undo the effects of previous calls.
