learnr 0.10.0 New features

Aggressively rerender prerendered tutorials in favor of a cohesive exercise environment (#169, #179, and rstudio/rmarkdown#1420)
Added a new function, safe, which evaluates code in a new, safe R environment. (#174)

Minor new features and improvements

Added the last evaluated exercise submission value, last_value, as an exercise checker function argument. (#228)
Added tabset support. (#219 #212)
Question width will expand to the container width. (#222)
Available tutorial names will be displayed when no name parameter or an incorrect name is provided to run_tutorial(). (#234)
The options parameter was added to question to allow custom questions to pass along custom information. See sortable::sortable_question for an example. (#243)
Missing package dependencies will ask to be installed at tutorial run time. (@isteves, #253)
When questions are tried again, the existing answer will remain, not forcing the user to restart from scratch. (#270)
A version number has been added to question_submission events. This will help when using custom storage methods. (#291)
Tutorial storage on the browser is now executed directly on indexedDB using idb-keyval (dropping localforage). This change prevents browser tabs from blocking each other when trying to access indexedDB data. (#305)
