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-3293: Use the new Spring's support for Hibernate 4 instead of Hibernate 3. Switch from using HibernateDaoSupport.getSession() to its getSessionFactory().getSession(). The latter is sure to close the session automatically while a session returned by the first method should be closed manually. Theoritecally we do it in OpenSessionInViewFilter, but it may not be always the case, leading to open Hibernate session being left behind.

Changed learning design activities and transition collections to use all-delete-orphan cascade management. This will ensure that the secondary records are created and removed as required.

This required fixing code that trigger cascade problems and also highlighted some session problems with the learner cache created by Jacky.

Moved the IBaseDAO and BaseDAO classes to their own packages and out of learning design. This interface and class may be used as the basis for any Hibernate DAO in the system - it isn't compulsory but it is a handy way of getting functionality. If we are going to be using it all over the place, having the classes in the learning design package is not a good idea.
