commit 4e6c497cd17d233731e2b885f107cf54411f9e7c
Author: John Ralls <jralls at ceridwen.us>

    Don't ask to save a non-existant book.
    
    To accomplish that we separate creating a book and creating a session;
    gnc_get_session no longer automatically creates a book if one isn't
    connected.
    
    We also add an initially_insensitive GtkAction array to
    gnc-plugin-basic-commands with a call to make its contents insensitive
    at plugin load so that the save button on the toolbar isn't lighted when
    there's nothing to save.

    Remove duplicate decl.

commit 8ff5af4c19838825c9bff2c5856e05cba53b910e

    Decouple QofBook creation from QofSession.
    
    So that we don't create two books when loading a session.
    Step 1 to not having a dirty book when we think we should have no
    book at all.
