* Update roxygen and regenerate.
Mostly just whitespace changes and `code` -> `verb`.
* R6 documentation for MockShinySession
* Install roxygen from GH
* % are now auto-escaped
(We still need to go find the rest)
* Fixed the ramining \% in roxygen
Found looking for ^#'.*\\% in all R files, so I believe this is all of them.
* Regenerate docs
* Decreate indent in roxygen so paragraphs don't get interpreted as code blocks.

* Namespace
* Add MockShinySession reference to pkgdown.
* Clean up test warnings
* Export session
These functions were temporarily ripped out of Shiny and moved
to the htmltools package. We've discovered that it's safe to
keep including them in shiny; as long as the functions in shiny
and the functions in htmltools are identical, the user won't
receive a conflict warning.
