Add ability to input where and when, a recreational event takes place.

[Hafpaf]

Ability to write where and when, a recreational event should takes place on the submission place.
Like on the talk submission page, it is possible to mark when you preferably want your talk, there is no similar option on recreational events submission page. It is only possible to write a note to the content team. This could alleviate some administrative copy pasting for the content team.
