US 06.01.01 (UPDATED) Optional Geolocation - 5 pts

[cbebe]

As a doer, I want a habit event to have an optional location to record where it happened.

Rationale - More details for habit tracking. May not be important for most types of habits but there are some where this would be helpful (e.g. walking for 30 minutes around your neighbourhood every day).

Story Points - 5

Risk Level - Low

Details - Check if app has permission to get location. If not, ask. Button for adding geolocation. Add map view???
