Display locations nicer

[LAMaglan]

Areas are grouped by locations. But it is a simple bullet point list, with areas separated by commas.
Example:
"""
sinnoh: sinnoh-route-229
johto: johto-route-29, johto-route-31, johto-route-35, johto-route-37, johto-route-32, johto-safari-zone, national-park, ilex-forest, johto-route-36, johto-route-34, johto-route-30
kanto: berry-forest, kanto-route-5, kanto-route-3, bond-bridge, kanto-route-12, kanto-route-25, five-isle-meadow, kanto-route-11, kanto-route-8, kanto-route-2, kanto-route-7, kanto-route-14, kanto-sea-route-21, kanto-route-24, kanto-route-13, viridian-forest, kanto-route-6, kanto-route-15, kanto-route-1
