Allow Web URL configuration for Swift and S3

The WEB-URL, that is different form the server url, is not considered at all when copying or opening the web-url of a file. It always tries to open the https server url.

I.e.:

Server URL:
cloud-server.something.com

Path:
/12345

Web-URL:
http://somedomain.com/12345
or http://somedomain.com/
Both don't work

Copy WEB-URL/Open Web-URL: Always providing https://tenantid:accesskey@cloud-server.something.com/12345/filename.xxx
