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.
LDEV-4381 Removed requestSrc parameter This parameter was responsible for passing integration server name to LAMS which was used on closing authoring and refreshing integration server page. This feature stopped working when authoring became Flash-less (as there was no more "Close" button). And now we decided to finally remove all its leftovers both in BB and LAMS sides. This change also involves removal of "isPostMessageToParent" parameter.
Besides, all Blackboard methods that deal with lams.properties file are now located in LamsPluginUtil only. All their duplicates in LamsSecurityUtil (e.g. LamsSecurityUtil.getServerAddress(..)) were removed
