Add info about archived status of cards

The idea is to run `update_suggestion_box` as a cronjob. Once a day/hour.. whatever suits best. If you wonder why I have done this on a separate script, and not included in the API call `/suggestions`, this is because Trello API is not precisely super fast, and I prefer this non-vital information to be 1h outdated than cause the suggestion box to load slowly because it has to fetch info from Trello.

Comments? :-)
Ah ha!! Nice, I presumed sb_database should be a 'list' or 'dict'. Dint think of a db object and "update" is a method of that object.. :satisfied:

Cool!! Merging it :+1:
