wget 1.16.1

This version bump also brings the --disable-pcre flag, and this commit makes that flag take effect unless you pass --with-pcre to the brew install.  Pcre is not a requirement, but wget opportunistically (and silently) links to it if it's on your machine, which can make for nasty surprises later.
I rely on the link provided in the cookbook to tell me how to properly "squash".  However, that link appears to be broken.  The following worked: http://gitready.com/advanced/2009/02/10/squashing-commits-with-rebase.html

The link in the cookbook has three leading "w"'s, and when I follow it Safari tells me it can't find the server "www.gitready.com".
