Set manual location

[RizzeKnight]

As a user, in order to access the content within a certain location (and to not be dependent on GPS-/network-based location data), I want to click a button 'Set location', and then* be presented with a map that includes a search function, navigate to a certain location, and confirm said location.
*One alternative/additional in the 'manual select' interface might be a directory/list of locations, rather than (merely) a map view

Based upon user input, a new map tile & subsequent location is loaded. The button 'set location' persists in this view, as well.

The error "user has denied location access" should be removed.
