type of port of url

[Masatake YAMATO]

Dear, Sir

I'm trying your url package.
I have a question about the port slot of url object passed to 
url-protocol, e.g. url-irc.

Is the port a string or integer?

In the function, url-irc, it seems that url-port is expected to return a string.
However, it returns an integer. Attached patch is required to use url-irc.el.

string-to-int is also used in some other places in url packages to
convert the type of port.
