[Feature] Improve player region display in global player search

[jiangtyd]

Currently, we display the region for which a player has the lowest uncertainty. This is okay, but could be hard to use for a region admin dealing with a player who plays in multiple regions.

There are a few possible solutions:

• Display the top 2 or 3 (lowest uncertainty) regions in the search result
• Allow admins to select a "primary region" from among the regions that player has played in (tricky because this could result in admins from different regions having a "tug-of-war" if they don't communicate)

So #186 actually will come with a function that will determine a Player's "Most Likely" region based on the quantity of tournaments they have entered in the past X days.
Unsure what X is at this point, can discuss further. 186 Should also come coupled with a way to do the second thing you suggested which is to manually set primary region.
