http: improved directory listing with new template from Caddy project
This includes a new directory listing template which was originally
from the Caddy project (used with permission and copyright attribution).

This is used whenever we serve directory listings so `rclone serve
http`, `rclone serve webdav` and `rclone rcd --rc-serve`

This also modifies the tests so they work with the original template which
is easier to debug.
