Add --update_business_templates support. This, used in conjunction of --load will force all business templates to be updated with filesystem-available versions. Also invoking with --save will cause updated site to be saved for future use.
Do not use objectIds to get the list of installed business template, but getInstalledBusinessTemplateList.
This allows to not specify the business template id at installation.
