Sections don't support negative keys

[drobota]

I would like to use negatives keys for sections
like :

last_section = page.my_sections[-1]

but due to this code it is impossible

    def __getitem__(self, idx):

        if idx < 0 or idx >= len(self):
            raise IndexError("Sections index (%d) out of range" % idx)
        for i, _ in enumerate(self):
            if i == idx:
                break
        return self

The way Holmium conflates sections and section elements is really surprising. I already fixed a bug in this method earlier this year where any index greater than 1 would fail. I think the correct fix for this is to overhaul the structure of the object model so that child items within sections are separate objects.

Thanks a lot
