Determine Most Current Version of Burp


When Burp does an automated update, it downloads the newest version of Burp to the current folder and leaves all previous versions intact.   This tweak will automatically determine the newest version.  This also elimiates the need to manually create the symlink (and recreate it for each new Burp update).
