Widget has table names hardcoded

Found more bugs in the events-widget.php

If have only single day events, those will not be displayed on the calendar widget. This is because the range will not satisfy.

Modified the code in the events-widget.php

function get_dates($start, $end)
    {

        $startDay = strtotime($start);
        $endDay = strtotime($end);
        $days = ($endDay - $startDay) / (60 * 60 * 24);
        $this->eventsData[] = date("m/d/Y", $startDay);
        for ($i = 1; $i <= $days; $i++) {
            $this->eventsData[] = date("m/d/Y", $startDay + ($i * 86400));
        }

    }
    /*for php 5.3>*/
        function get_dates_5($start,$end){

        $begin = new DateTime( $start );
        $end = new DateTime( $end );

        $interval = DateInterval::createFromDateString('1 day');
        $period = new DatePeriod($begin, $interval, $end);
        if(empty($period)){
          $this->eventsData[]= $begin->format( "m/d/Y" );
        }else{
          foreach ( $period as $dt ){
            $this->eventsData[]= $dt->format( "m/d/Y" );
          }
        }

    }
