Support for changes to the types module

[cheeming]

E.g. TupleType has been changed/removed.

@cheeming : Could you please paste some sample code and how you would like python-future to support it?

I expect that you may want to convert this code:

isinstance(t, types.TupleType)

to this:

isinstance(t, tuple)

Do this meet your need? Would you like futurize to convert this automatically?

[cheeming]

Yes.

Actually I stumble upon this when I tried to use this library in Py3.
I have added the code into github.

On a somewhat unrelated note, the copyright on the example code you posted is a little confusing...
