add detection for port argument type

[sunng87]

I Know that fapws3 uses getaddrinfo internally which receives port as char*. However, most inetaddress api take port as an integer. To make the api of fapws3 portable enough, I suggest you to add a type detection on the port argument. If integer input detected, just convert it to string.

Fapws3 broke backward compatibility very bad this time. The wrong type segfaults and there is no way to detect the expected type from within python.

In addition, please add a version attribute. The next time fapws3 breaks APIs we can at least special-case the release and work around such things.

until version 1.0, backward incompatibility could occurs. The switch to string was reported on the blog and mailing list.
