LIVEOAK-47: Minor bug fixes to the script module.
Install Example Applications improvement
Install uses specific endpoint for copying contents to app folder;
Import reads application.json and creates the app through regular endpoints;
Actually pass in the directory to ApplicationDeployerService, as we have it, so it doesn't have to be recreated
Refactor LiveOakFactory to use the same services as WildFly subsystem to prevent code duplication.
 - Also changed ApplicationsDirectoryService to not default the directory if it's null, and to use ApplicationsDirectoryPathDefaultValue in conjunction with MSC DefaultValue instead
Adjusting Installed badge in example apps
