Problem and impact

In order to be able to quickly check in speakers when they arrive, this should be possible on the speakers' details pages or even wherever speakers are mentioned, on the speakers tab for a submission for example. The latter would for example help when all speakers for one talk arrive at the same time.

Proposed solution / feature

Ideally, I'd be able to check in speakers whenever the speaker name appears on my screen.

On the speakers details age, the "Mark speaker as [not] arrived" button could be in to top left, where the Links section is placed on the Submissions details page, next to the "Reset password" and "Send email" buttons.
In the Speakers tab of a submission, the "Mark speaker as [not] arrived" button could be placed nearby the "Send email", "Edit" and "Remove" buttons.
