LI-161: Generate special version of deploy.xml for tools that has a generic parameter in the place of the drive paths. This is turned on in common.properties (generate for installer) in lams_build. Only use this option if you are writing an installer/updater.
Change to tool deployer so that scribe is hidden correctly when it is updated. Ie its valid flag is set in lams_tool and disabled in lams_learning_library
