Fix authentication error viewing ZMI resource with virtual hosting (#…
…1204) * ZMI: re-implement the logic to prepend authentication path The previous approach from #1196 was not correct when using virtual host, because AUTHENTICATION_PATH is not usable in virtual host contexts. This uses a different approach, by making the js and css path subscribers take care of generating the URLs with the authentication path prepended using request API aware of virtual hosting. * ZMI: use /++resource++logo/ for public resources /++resource++zmi/logo/ and /++resource++logo/ is the same folder on disk, the former is protected by Manage portal and the later is public. Protected resources were problematic, because we want to serve them from the root, but the manager user might not have permission on the root. * ZMI: include zmi.localstorage.api.js using js subscriber Using this approach we serve a resource relative to the path where user is authenticated. * copyright.dtml: update bootstrap URL This was referencing an old URL.
