Automatically generate map Id and Name

Currently the imgmap.prototype.getMapInnerHTML function takes care to
create the id and name for the map if they are empty, but if that function
isn't called then they will be empty by default.

The solution is to move the existing code to the getMapId and getMapName
functions:

imgmap.prototype.getMapInnerHTML = function() {
    var html = '';
    //foreach area properties
    for (var i=0; i<this.props.length; i++) {
        if (this.props[i]) {
            if (this.props[i].getElementsByTagName('input')[2].value != '') {
                html+= '<area shape="' + 
                    this.props[i].getElementsByTagName('select')[0].value + '" alt="' +
                    this.props[i].getElementsByTagName('input')[4].value + '" coords="' +
                    this.props[i].getElementsByTagName('input')[2].value + '" href="' +
                    this.props[i].getElementsByTagName('input')[3].value + '" target="' +
                    this.props[i].getElementsByTagName('select')[1].value + '" />';
            }
        }
    }
    //alert(html);
    return(html);
}

imgmap.prototype.getMapName = function() {
    if (this.mapname == '') {
        var now = new Date();
        this.mapname = 'imgmap' + now.getFullYear() + (now.getMonth()+1) +
now.getDate() + now.getHours() + now.getMinutes() + now.getSeconds();
    }

    return this.mapname;
}

imgmap.prototype.getMapId = function() {
    if (this.mapid == '') {
        this.mapid = this.getMapName() ;
    }
    return this.mapid;
}
