    Reduce the number of times the register loads - Update
    
    In the previous update the changes to 'double_line mode' and 'register
    style' were not catered for so this commit fixes that by using a stored
    value 'enable_refresh' in the GncPluginPageRegister. This value is used
    to enable/disable the triggering of gnc_ledger_display_refresh command
    instead of passing a parameter as these settings are triggered by call
    backs. The value is set to FALSE in ...recreate_page before restoring
    all settings and subsequently set to TRUE after so normal refreshing
    can occur. This reduces the potential number of refreshes on load from
    7 to 2.

    Bug 796839 - Find transaction won't filter on Date Posted
    
    The results of the find are displayed in a search_ledger but with reset
    filter settings. As part of the initial setup of the filter, the
    SPLIT_RECONCILE and TRANS_DATE_POSTED parameters are purged from the
    query and so if 'Date Posted' was used, all transactions were displayed
    so this commit tests for a search_ledger and stops the purge along with
    saving the query for subsequent use in the filter dialogue.
