Location name hints should be separate from the name

[jace]

As demonstrated in hasgeek/hasjob#373, Hascore currently adds hints to the name such as "(state)" and "(country)". This is necessary for ambiguous cases like Pune (city and district), Delhi (city and state) and Singapore (city and country). However, it's not necessary when that ambiguity doesn't exist.

Hascore should return the title and hint as separate fields, and let the client app display the hint only when necessary.

Hints also need language localization, a separate concern.
