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-4415 Add tool output weight. Rewrite activity evaluations.

Activity evaluations have been implemented as a list, even though always

only the first element is meaningful. They were rewritten as one-to-one

association with Activity. The primary key is activity ID now instead of

DB generated UID.

Weight column was added.

Server version was bumped so a filter can pick up activityEvaluations ->

evaluation field rename when importing older LDs.

A convention without date was used for server version as it seems good

enough.

Unnecessary versions of clients were removed from configuration table as

they server the abandoned Flash authoring.
