You can now pass in an info field with a value
like "out to lunch" to the /users/me/status,
and the server will include that in its outbound
events.
The semantics here are that both "away" and
"status_text" have to have defined values in order
to cause changes. You can omit the keys or
pass in None when values don't change.
The way you clear info is to pass the empty
string.
We also change page_params to have a dictionary
called "user_status" instead of a set of user
ids. This requires a few small changes on the
frontend. (We will add "status_text" support in
subsequent commits; the changes here just keep
the "away" feature working correctly.)
We now have single function that handle both away
and not-away.
This refactoring sets us up to piggyback "info" more
easily onto status updates.
The only thing that changes here is that we don't
delete database rows any more when users revoke
their away status. Instead we just set the status
to NORMAL.
