    [balsheet-pnl] refinements to barchart
    
    * barchart should inherit the period selected. this requires
      redefining the periodlist - we need the exact symbol to set the
      barchart's period option.
    
    * balsheet: disable barchart if period is disabled - it makes no sense
      to create link to networth barchart for single-date balsheet
    
    * reorder some options for better usability
    
    * note this may affect saved-reports / saved-tabs but only those
      running bleeding edge maint. I do not intend to make any further
      options changes on this report.
