The activity Start Stop Continue is now renamed Retrospective and allows for any section-split retrospective styles, including, but not limited to, Start Stop Continue. Upon commencing the activity, the Presenter can select section headers from a list of presets, or, enter their own custom headers. Participants will have the section names as buttons on their device when submitting responses.

Additionally the activity now saves state to localStorage, allowing presenters to export data even after closing and re-opening a lobby. | PR
