Added a functional deadfly utility

Attempt to patch the deadfly command. This file parse and store data about an adf.ly URL.

You will need to implement this in DeadflyCommand.java,

private static final Adfly adfly = new Adfly();

And to get the deadfly-ed link:

adfly.update("http://adf.ly/link");
String link = adfly.getResult();
adfly.reset();
