commit 1a4f27f6b3b4d3ae2e9263396b32e684f434c96b

    [html-utilities.scm] deprecate gnc:html-make-exchangerates
    
    Because old exchange rates function used exchange-fn which converts 1
    commodity into domestic currency; new exchange rates uses price-fn
    which queries the gnc_numeric pricedb entry directly.

    Bug 797982 - exchange rates' decimal places
    
    use gnc:html-make-rates-table instead of gnc:html-make-exchangerates
    to show effective exchange rate or price used

    [html-style-info.scm] price-renderer does not convert to decimal

Date:   Mon Oct 19 20:08:44 2020 +0800

    [gnc-pricedb.c][api] pull out composite pricedb price retriever
