Update py-pandas to 0.11.0.

Summary of changes since 0.10.1:

This is a major release from 0.10.1 and includes many new features and
enhancements along with a large number of bug fixes. The methods of
Selecting Data have had quite a number of additions, and Dtype support
is now full-fledged. There are also a number of important API changes
that long-time pandas users should pay close attention to.

* New precision indexing fields loc, iloc, at, and iat, to reduce
  occasional ambiguity in the catch-all hitherto ix method.

* Expanded support for NumPy data types in DataFrame.

* NumExpr integration to accelerate various operator evaluation.

* Improved DataFrame to CSV exporting performance.

For a full list refer to the "what's new" page.

Also fixes PLIST errors introduced in last update.
Note update of math/py-pandas to 0.11.0.
