Favorite/Starred Players

[aronduby]

While contemplating #135 I thought it would be great to have one of the shortcuts be a link straight to your kid's page, but shortcuts can't be dynamic like that. So, what if we had the ability to star/favorite/whatever a single player (or maybe a group of players) so a single endpoint could do one of the following things:

• If there's only a single selected player, then it just redirects to that player
• If there are multiple selected, draws the interface with the selected called out at the top
• If there are none, it falls back to showing the full playerlist interface

This would have to be tracked client side since we don't have accounts (yet) and I don't want to try doing shady tracking things or anything like that. So the idea is a super light weight initial page that checks for the client side to do any redirection. Then the player list page gets revamped to do starred, probably add that to the player page header as well. Maybe even a link in all the headers/menus for the favorites?
