LDEV-2080: For all remaining tools - changed the way Hibernate properties are declared. Even for tools that did not need it the file was changed, so usage is the same everywhere.
LDEV-1606: Deploying classes both in tool's JAR and WAR files led to duplicate imports while trying to make Core Session Facory to be aware of tools' classes. Classes are not deployed in WAR files anymore, since they are not needed. Core Session Factory gets mappings of all the deployed tools.
