Calendar - follow naming conventions

[dmitrig01]

I see this all over the place - <a class="calendar_close" onclick="popUpCal.hideCalendar(0);">Close</a>

That should be <a class="ui-calendar-close">Close</a>, and the event should be bound with a $().bind('click', function(){...});

That is how it was coded initially, but we realized huge performance increases by simply setting the events inline.
