Add a switch to allow redirection to be followed with depth, -dN with N = 0 for infinite redirection, or N > 0 for N redirection
Currently, $urlget() gives up after 10 redirects. It does not detect cyclical redirections. As far as I know, most browsers have a redirect limit of between 10 to 20 redirects. Instead of adding an option for this, I would rather make it behave in a standard way. I could increase the limit to 20 but 10 seems reasonable? I would not want to allow infinite redirects.
