LDEV-4381 Remove obsolete lamsAltServerUrl setting This setting was used by lams_ld_template and lams_ld_template_blackboard projects. It was intended to solve the original issue related to LAMS having to run as http:// for the video streaming tool, but needing https:// to keep the iframe communication happy. But once everything was switched to https there is no need in this setting.
NTU-13 Switch log4j to slf4j logging library As long as Blackboard doesn't cope well with log4j we switched to using slf4j library. It will log messages to stdout-stderr-xxx.log file.
