    Merge branch 'block-pref' of https://github.com/Bob-IT/gnucash into maint

commit b6f2b111bc2b9e701639eb4684bdbfe4bf4b97c9

    Block registered prefs when preference dialogue loaded
    
    When the preference dialogue is loaded and options are set, the ones
    with registered callbacks fire causing parts of Gnucash to be updated.
    This was observed with gnc_split_register_load being executed 5 times
    for each open register when the preference dialogue was loaded.
    
    To overcome this, a couple of functions have been created to block and
    unblock all registered prefs and used while the preference dialogue is
    loaded.
