v0.0.11 Feature

This commit contains:

• Bug fixed in historical graph when users enter lowercase symbol the graphs doesn't show which is caused to external API that does not like lowercase symbols.
• Historical Graphs are now preserved in the reserved order (like a stack) and you can clear the graphs by clicking the button.
• You can specify the format like 100 SBD that will be converted to your local currency and BTC
• The users now can enter arbitrary number of days in the historical tab. Also, if a number is less than 3 days, the API of minute will be called. If it is between 3 to 7, then API of hour will be called otherwise API of day will be used.
• Code Refactoring e.g. the random_id is provided to improve the code robustness.

New format is supported (easy to use)

Conversions are done on the fly.

Graphs are pushed to the bottom and you can clear the tab via Clear Button.

Javascript code that deals with the new format

if (pair.length == 2) {
    let a = pair[0].trim().toUpperCase();
    let b = pair[1].trim().toUpperCase();
    if (isNumeric(a)) {
        if (isValidSymbol(b)) {
            let dom = $('div#conversion_results');
            let dom_id = "convert" + random_id();
            dom.append('<div id="' + dom_id + '"> </div>');
            getConversion(b, "BTC").then(x => {
                $('div#' + dom_id).html("<h4>" + a + " " + b +  " = <span class=yellow>" + (x * a) + "</span> " + "BTC" + "</h4>");
            });                    
            if (local_currency != '') {
                let dom = $('div#conversion_results');
                let dom_id = "convert" + random_id();
                dom.append('<div id="' + dom_id + '"> </div>');
                getConversion(b, local_currency).then(x => {
                    $('div#' + dom_id).html("<h4>" + a + " " + b +  " = <span class=yellow>" + (x * a) + "</span> " + local_currency + "</h4>");
                });                                            
            }
        }
