commit 7003a561712d104e6b72dc5be2c6bdaff0ff20a7

    Make gnucash 2.7+ rerun bayesian data conversion whenever needed
    
    Whenever recent 2.6.x versions of gnucash store bayesian data
    in the old format (full account name based), gnucash 2.7+
    should perform a conversion the the new format (guid based)
    on subsequent opening of the file.

    Allow matching accounts to be found also by their GUID
    which will be used in newer versions. The
    default behaviour is still to create new entries
    under the account fullname.

commit 712d340bf4d7898605e6fb8e6a4a9b52c0372410

    Introduce GUID_BAYES feature flag
    
    This will be set by future versions of gnucash (2.7+) when
    they save bayesian data using GUID's instead of full
    account names. The flag will prevent older versions
    (2.6.11 and older) from opening data files with such data.
