adding a security/safety check to lower the possibility that someone could intentionally overload the system by creating huge quantities of basket contents, required adding a parameter, so updated version to 5.03
backing out a change I made, because it does not work well for the action copy-paste version. Instead, adding the full pathname for createdb and an explanation why the instruction uses fullpathname, when it would not be necessary for user pgsql
Added elements subsite_node_id, subsite_url, vhost_subsite_url and vhost_package_url to allow includes and master templates to vhost aware server relative urls.Added subsite::get_url to allow functions to generate vhost aware absolute urls.
