stache system plugin needs nodeList

https://github.com/canjs/canjs/blob/master/view/stache/system.js#L26

nodeList needs to be passed in as an argument on L26, then passed in the returned function on L31.

Pseudo-test case is:

var nl = [];

//note: we'll need to import a template to test the stache! plugin
//create template with above node list set manually

//register helper, should receive above node list; currently this does not
can.stache.registerHelper('helper', function(options) {
    equal(options.nodeList, nl)
});
