Introduce EMailBackend into libevolution-mail.

EMailBackend is an abstract subclass of EShellBackend that handles
online and offline modes and application shutdown.  Placing this in
the shared mail library allows Anjal to reuse it.  Evolution's mail
module further extends this class as EMailShellBackend.
