Some Updated Current Classes Reports

I updated five of the Current Classes reports in the Live Schedules reports area.   Two of the reports are free (Current Classes - Students and Current Classes - Teachers) and three are premium (Current Classes with Daily Attendance, Current Classes with Meeting Attendance, Current Classes (PST)).  The two free ones and the attendance ones all look at where students should be at the current time, but they could give incorrect information due to server times being different.  The coding is similar to the sql used for the Find Me alert, so instead of using sysdate and pulling the time from the database server, I used the ~[] the alert uses, which pulls the time from the application server instead.  I also updated the two attendance ones to show students who are not scheduled at the time.  The one for the teacher portal - Current Classes (PST) - was updated to show students not scheduled in the period that was chosen.
