Subject: [PATCH] Update base.py (#1099)

Modification necessary for using CVAT from remote machines when accessing with FQDNs
See https://github.com/opencv/cvat/issues/1011#issue-542817055
and https://github.com/opencv/cvat/pull/1098

"I believe the reason for this is that sometimes if the port number is :80 and the URL is not in the LAN (:port), but instead it is a Fully Qualified Domain Name (:port), the port 80 is redundant (mydomain.com:80) and the errors arise."
