Implement ActiveX obfuscation for minified dist
Implement ActiveX obfuscation for minified dist

Some coporate proxys/firewalls (such as Blue Coat) filter out JS files
that contain the string 'ActiveX' in them. This patch alters the Uglify
AST so that all occurences of the string are obfuscated, making
socket.io work in even the most hostile environments : ).
