feat: property reputation from visitors, resistant to farming

Browse Source 
Property worlds now give their property reputation for the time other people spend on it, which
fills the property lists and the news screen's Today's Top Properties. Visitors are counted per
account; the owner's account, accounts linked to it and staff don't count. A visit earns nothing
for the first property_reputation_min_visit seconds (WorldConfig's propertyReputationDelay), then
each active minute (the visitor moved) earns reputationPerMinute times a multiplier, for a capped
number of minutes per visit. Repeat visitors earn less the more recent days they already gave
reputation, and each visitor and each property have a daily cap. Every parameter is a setting;
what each account gave each property per day is kept in property_reputation_visits. The rules are
pure functions with unit tests.
