    Bug 797453 - Chart of Accounts is slow to update / redraw
    
    The chart of Accounts tree view gets redrawn often and gets the data
    from the model via gnc_tree_model_account_get_value(). As such the
    numeric values are constantly being recalculated on every draw which is
    not ideal. This change caches all the string values to a GHashTable for
    retrieval which should be quicker than before.
    Changes to an account will clear the cache for that account and its
    parents so values can be updated. Changes to the preference negative
    colour clears the whole cache.
