* wpv_render_datepicker
*
* Renders the datepicker for date based frontend filters
*
* @param $url_param (string) the URL parameter used on the frontend filter
* @param $date_format (string) the date format to use when displaying the selected date besides the datepicker
* @param $default_date (string) the default date to be used when there is no value passed by the URL parameter - special case NONE
*
* @return (string) containing the needed inputs
*
* @since unknown
*
* @note $default_date default value was changed in 1.7 from NOW() to NONE; empty will mean NONE too
*
* @todo add an attribute for themes http://rtsinani.github.io/jquery-datepicker-skins/ 
* OR better an option in the Views settings, because we can not have two different styles for two datepickers
