LDEV-1825: Change in order: activities from DTO are parsed first. This way we can check for the activities with unwanted elements (groupings, branching mappings). These elements are then removed from DTO so they don't get into XML.
LDEV-1912 set session timeout programmatically according to lams' UserInactiveTimeout value via a servlet listener rather than hard coding to 120 mins (in some webapps, no session timeout was specified at all).
LDEV-1910 hibernate loses branch_activity_id value when association is uni-directional, make it bi-directional. Putting link in the top level Activity class rather than BranchingActivity because of new work for LDEV-1299 that will allow more types of Activities to be mapped to branch_activity_id in lams_branching_activity_entry
LDEV-1911 Making Gmap tool have its own config page for the gmap API key, istead of putting it in the general lams configuration page.Removing the gmap config item from the lams_configuration table (actually just removing the insert so it is never inserted)
