Improve hive location selector UI

[adzialocha]

Curious what the HiveLocationTypeSelector looks like when overflow occurs? I see the implementation uses Wrap which I guess means it'll just move onto another line. wondering if it would make sense to do a horizontal scroll on overflow instead, and change the minimum width of the buttons to make them more square by default (but let them grow wider if the associated copy is very long).
