Resolves issue #19 added --no-cookies boolean and --header array parameters 

These options are necessary in certain cases, most commonly to bypass the checkbox security when downloading Oracle's JDK packages, 
e.g 
wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u5-b13/jdk-8u5-linux-x64.rpm

I avoided using stdlib as seems to be the preferred stance for this module.
