support deque in objgrep

[glyph]

This is an outgrowth of #1134, but maybe it would be useful on its own.

[glyph]

Committed to branch dqog-2323.

At the very least, testDeque should be test_deque and have a docstring. Are there any arguments against adding this though? I personally can't think of any.

[therve]

I'd to use a bit of duck-typing here to test list-like objects and not rely on isinstance.

[exarkun]

You really need to do type checking here because that's the only way to be certain you are correctly accounting for references.

Unless you do something entirely different instead.

I'd like to see something based on gc.get_referents(), since that will work for pretty much any type.

[therve]

Added a few docstring, and change method names to conform new standard. The patch is against the branch.

Might be nice to update the types.ListType and types.TupleType on the changed line in reflect.py to just be list and tuple.

Changes all look good. Make the above change if you want, and merge.
