LDEV-1280: Implementing assign groups to branch in monitor screen (for define later). Required adding new functionality to branch related objects and a new call in lesson that allows monitoring to check if the branching activity has been attempted (we don't let the user remove groups or users from a branch once the branching activity has been commenced). Also moved the UTF-8 ajax fix to a common class in lams.jar so it can be used for all AJAX calls if desired.
LDEV-1134: Fixed the View Branches screen for tool output based branching - I can't list the users based on groups as they aren't in groups (and I can't put them in groups as the groups have to be linked to the condition and if the user goes to the default branch there is no condition). So for tool output based branching I have to find the users via their progress records.
