javascript compression fails when using delete as function name on object

[jbhamilton]

When an object has a method named "delete" the compression fails

Ex:

SC.delete('/resource',function(){
});

Error:

Same issue as #47 - requires ES5 support in Rhino to fix.

SC['delete']()
It should be compiled
