Feature/multi sections

This branch contains the changes  to properly display the section count after sections are created and edited in the sections list page. 
I may be missing something obvious (it's something I never rule out), but if I was to do: 

   enrollment_count = 0
   if (enrollment_count):
      print "true"
   else:
      print "false"

the code would print "false". Is that not what would happen here if the count is zero?
