LDEV-3742 Add Like feature for Scratchie * Implementation is a bit different for WF branch, as GET_BURNING_QUESTIONS_WITH_LIKES SQL query in ScratchieBurningQuestionDAOHibernate.java should be rewritten to comply with SQL92 standard introduced in MySQL 5.7.5
LDEV-3347: Revert to default caches' settings as "entity" cache config is a template for a region (one Java entity = one region). This is different to JBoss where all entities were stored in single region and it had to be large. Add missing parameters in Hibernate config.
LDEV-3760: Initial implementation of notifications. Add new delivery method to EventNotification framework. Allow notifications on file upload in Share Resources. Add notifications button on home screen.
