This isn't quite right. evolution-wombat *is* the local calendar, local
addressbook, and LDAP addressbook backend. You cannot plug other things
into it. Instead, you create an additional component that supports the
GNOME_Evolution_Wombat interface, and the calendar gui will launch it as
needed for the URL types it supports.
