Some valid URLs are not recognized correctly

[allo-]

When you try to add http://someserver:8080/some/path, webcatalog does not recognize it as valid URL.

I think it's because someserver is not valid domain or IP.

This may be possible, that not the port is the problem, but that this is just a hostname in my LAN and no FQDN.
But it is a valid URL and when disabling the is-url check, I can use webcatalog to access it.

The alternative would be to use a pseudo domain like .local, but I do not do this in my normal browser either.

There's a PR for this segmentio/is-url#16. But nobody has merged it yet. :(

It looks like the PR is only adding tests?

What about just including the relevant code instead of loading the module to avoid waiting on upstream?

Another option: Use HTML5 Inputs instead of validating yourself? This seems to be the right place to do it, if we assume that users have a recent browser backend.
