all.snippets: bbox and box snippet Python 3 compatibility

I'm not much of a python pro, but it appears the correct
way to iterate is next(i) instead of i.next().  i.next() has
been renamed to i.__next__() on python3, but next(i) works on both.

Pasted below is the following test script ran through python
2.6, 2.7, and 3.3:
i = iter("1,2".split(","))
next(i)
i.next()
i.__next__()
next(i)
