Bug in fuel.transformers.sequences

[mwong009]

In line 81: self.index += 1, iterations are moving 1 frame at a time, even if offset was initialized >1

line 81 should be self.index += self.offset instead of self.index += 1

I don't see why this is a bug, because the two don't necessarily need to be the same. I guess it would be nice if the stride of the transformer could be configurable, but this would be a new feature, not a bug fix.
