LDEV-1134: Branching: View screen for the class export portfolio. Required refactoring of classes and moving the system tool link to move to an interface.
Jira: LI-130. Fixed update-lams.sh such that JAVE_HOME is now taken from the JDK_DIR variable in lams.properties and does not need to be explicitly set prior to updating
LI-131: update-lams.xml now compares the news.html with the 2.0.2 version of news.html and if they are the same, it replaces it with the 2.0.4 version, otherwise (if the user has modified it) it leaves the existing news.html intact
