Doesn't sanitize for in loops

[davidlukerice]

All the for (var j in x) loops don't check x.hasOwnProperty(j). This breaks rstats whenever an app also uses a library that extends the array prototype. Or just iterating using a normal for loop works as well.

Fixed with 7868e05

Normal for loops or array.forEach are not good when using arrays as maps, since I need the key and the value. And it's debatable if people should go around messing with the native objects prototypes!

Anyway, easily fixed.

Thanks for the quick fix! Although I agree messing with the prototype is a bad idea, I'm currently reliant on a library that does this.
