src: don't obj->Set(Integer::New(...), val)

Don't create an Integer when setting a numeric index on an object or an
array, use the version of v8::Object::Set() that takes an uint32_t.

Change the types of the variables from int to uint32_t and clean up
some code consistency issues while we're here.
