[IronPython] Special method lookup

[Dino Viehland]

Thanks for the bug report - we're actually aware of this issue.  I made some small fixes while fixing other bugs that corrected this in some spots, but not all...  I've gone ahead and opened a bug to track it (we didn't have one before) so we'll get it entirely cleaned up for the next release.

Do you want to help develop Dynamic languages on CLR? (http://members.microsoft.com/careers/search/details.aspx?JobID=6D4754DE-11F0-45DF-8B78-DC1B43134038)

Python Reference Manual 3.3. The wording is not the best. Should file a doc bug.

"For instance, if a class defines a method named __getitem__(), and x
is an instance of this class, then x[i] is equivalent to
x.__getitem__(i)."

In this case, although x.__getitem__ exists, x is an instance of a
class which *does not* define a method named __getitem__(), so it
should not be called.
