modified modals to show sectionGrouping if exists
modals now account for different batch actions
unified modification server method to update q's
sections retrieved for batch operations
handle different actions for edit, remove, add
now pass q/a types, auto reload on save success
pass along sequence instead of questionid

We won't change questions directly, even for remove/edit, but instead
change matching questions depending on batch scope.
add/remove w/modal now using knockout

makes it a lot nicer than dealing with the dom directly
moved edit to knockout and consolidated modals!!!
question has reference to parent

allows access to sectionType and other info
filter by matching sections and actually do POST
show notification for success of bulk action
