Integrate multis into main accounts
The purpose of this is twofold: * Allow players to navigate their main/multi accounts without having to log in and out. * Synchronize things between the two accounts when it doesn't make sense to have two values (i.e. e-mail address, user preferences, bans, etc.). Add a new table `account_link_login`, which associates a `login_id` (the new primary key replacing `account_id` in the `account` table) with an `account_id` (the primary key of `account_link_login`). Each "login" (`account`) can be associated with multiple "accounts" (`account_link_login`). This is a little confusing, since ideally the `account` table would be renamed `login` (or similar), but we are probably a bit too heavily invested in the original infrastructure to completely change it now. We provide a way on the "Play Game" page to switch to/create multis, including an option to link an existing account as a multi. Adds two helper methods to SmrAccount: * getLinkedAccountList - finds all accounts associated with login * getLinkedAccount - returns an account if it is associated with login
