Bug 668479: Missing transport-only accounts in Preferences

Evolution kinda sorta supports multiple identities by allowing users
to set up so-called "transport-only" accounts by choosing "None" for
the account type.

Add a CamelStore subclass for those types of accounts so they get
added to EMailAccountStore.  It's just a stupid hack to keep another
stupid hack working, but this should sustain us until we can support
multiple identities FOR REAL.
