Now the StatusView (bottom-left corner, right below the room list) can
be used to set the nickname and status not only for all accounts at
once, but for managing the status/nick of individual accounts.
AccountManager now can set details of a single account, too.
MainWindow is no longer an Observer (as it just passed the information
along to StatusView― now StatusView manages that itself).
NicknameTextControl was removed, not being in use.
Now all account menus will have the pretty protocol icons to go with
them. :)
The icons are scaled to text-size so that they might be displayed in a
corresponding MenuButton, or maybe BMenuField at some point, and put
into the ImageCache.
The menu items do not have ownership of the bitmaps.
CreateAccountMenu() is used to populate a BMenu with items corresponding
to the map of accounts provided to it― but when an account is disabled
or enabled, it can't update automatically.
A dedicated class, fAccountsMenu, now replaces it― it'll automatically
repopulate the list whenever the active accounts update.
