[PATCH] Follow redirect to find HTML Title

Hi folks, Sometimes, when running showHTMLTitle.nse, the default page (at which the script is targeted) is not at "/" and the host returns HTTP Status 301 or 302. On the basis that the server may be telling us where the default page is at, the attached patch allows the script to follow the redirect (once only) as long as it's at the same host. Of course, there could be some other reason for the redirect, such as preventing access to "/" based on User-Agent, but I thought I'd throw the patch out there in case... Regards, jah
