Fixed Kinetic export problem

hi,

I've created a patch so kinetic works with meteor's new namespacing system. 

Unfortunately it's not pretty because I had to change the actual kinetic file for it to work. Only variables that are package-global can be exported. The Kinetic object is declared with a 'var', so to meteor it's only visible locally. I had to remove that, now it apparently works. 

As I said it's not pretty but here you go. 

Btw. I'm quite the github n00b, so if I'm doing anything wrong just tell me ;)
