/* basic idea of choosing global presence it to make it reflects the presence
* over all accounts, usually this is used to indicates user the whole system
* status.
*
* If there isn't any account, currentPresence should be offline, since there is nothing
* online.
* If there's only one account, then currentPresence should represent the presence
* of this account.
* If there're more than one accounts, the situation is more complicated.
* There can be some accounts is still connecting (thus it's offline), and there can be
* some accounts doesn't support the presence you're choosing. The user-chosen presence
* priority will be higher than standard presence order.
*
* Example:
* user choose to be online, 1 account online, 1 account offline, current presence
* should be online, since online priority is higher than offline.
* user chooses a presence supported by part of the account, current presence will be
* the one chosen by user, to indicate there is at least one account supports it.
* user choose a presence supported by no account, current presence will be chosen
* from all accounts based on priority, and it also indicates there is no account support
* the user-chosen presence.
