LDEV-2033: Initially MC tool was designed to accept multiple answers for a single question. This functionality was partially removed and together with saving all the answers provided by the user, it prevented answers to be correctly categorised (correct/incorrect).
Add changes so now we can see the difference between Learners and Teachers doing a preview (we can display Next Activity button from the begining if you are a teacher, so they don't have to submit a preview before go to next activity)
LDEV-2022 Presence now loading in all browsers, flash and flashless interfacesRooms were being created on the fly as a first user joined a lesson. If this first user happened to be using IE, no other users afterwards would be able to join. Rooms are created immediately from the wizard module now, through a servlet call to smack, which solves the problem.
