LDEV-3660: Remove export potfolio resources: Java classes, JPS, DB entries and labels. Remove localLinkPath attribute from CSS tag as it was only used for export portfolio.
LDEV-3653 Add websocket server and client code. Add Ant code for deploying the server class to <WAR>/WEB-INF/classes folder for WildFly to pick it up on start up. Rearange, clean up and formatting.
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.
