Replace CreateAccountMenu() with dedicated class

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.
