add location context and split out action and context views

arminta7: I turned off the stakeholder's view because I still actually don't understand it lol. At first, I thought it would be a view that would show all tasks with either a project or a person, but that's not correct is it? The "stakeholder" term itself is confusing. I would personally find that view more useful if it was one of two things: 1. a view to show any tasks with people, places, projects etc. I might label this "Contexts" like GTD. 2. a view to show any tasks with those action tags (#promisedTo etc). I might call this "Actions". Of course, this is just my personal opinion because stakeholder doesn't apply to anything in my world! Also, what qualifies a task as aging?

zsviczian: I will do two changes. 1) add places as a filter 2) split out the view for contexts and actions
