Location Completion

[danirabbit]

Problem

location completion is something we need to do in at least a few places:

• Adding location to a Calendar event
• Adding location to a reminder in Tasks
• Searching locations in Maps

It's fairly complicated if we want to provide consistent results with place icons and good descriptions etc

Proposal

I think the most drop-in solution for developers would be something like a Granite.LocationSearchEntry that returns a Geocode.Location

Prior Art (Optional)

The location search in Maps is pretty decent in terms of nice formatting location rows with colored icons etc
