LDEV-3115 Fix group removal on LD save in authoring

It seems that Hibernate does not like having entities violating unique keys in one collection. Even for a while and even though afterward the collection contains only unique entities.

LDEV-4696 Reintroduce a failsafe for missing branch activities set

There are normal situations where the collection is null. It needs to be

checked before attempting to add something.

LDEV-4696 Make all @ManyToOne and @OneToOne lazy

Hibernate 3 used lazy loading of single-object relationships by default.

JPA's default setting is eager. When loading entities all references are

loaded immediately using JOINs. A large entity, like Learning Design,

can have a query consisting of 25 JOINs. It makes it very slow.

There is no way to change JPA's default behaviour. In order to make JPA

annotations behave like old Hibernate, each of them got an explicit

attribute saying that loading is lazy.

LDEV-4507 Prevent duplicate groups with a DB constraint

Lesson staff groups need to have order id different than 1 so they do

not clash with learner groups.

Fetch lesson learner count faster by an exact query rather than fetching

all learners with Hibernate and counting them.

LDEV-3614: Improve processing of Gate activities. Alter lams_activity_learners table so it reflects its real purpose: storing learners who are allowed to pass a gate. Find out who is waiting in front of a gate using learner progress (activity attempt). For sync gate take into account all possible lesson learners (lesson class) rather than only ones who started a lesson. Use an entity in JSP generation rather than a DTO which is just a wrapper for the entity. Code clean up.

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: Preview now lets the author select a branch to view, but the author can only do one branch. To view all branches, the author needs to run preview multiple times. Did some small refactoring to have only one piece of code that creates the branching mapping related to a group as we have many bits that need to do this (authoring, import, chosen branching in monitoring and now preview!)
