Log Message:
Update py-rpy to 0.99.0

New features:
* Dramatically simplify the build process for Win32
* It is now possible to use setup.cfg to control various aspects of the
  build process. 'config.in' contains a template containing all available
  options and what they do.
Bug fixes
* RPy compiled with Numeric support will no longer crash when run with
  Numeric available.
* Crash during import when R is missing from the registry
* Problem using R Wavelets library with RPy
* RPy does not build on OS X, easy fix
* Plotting with RPy crashes Python
Other
* The rpy.py now communicates RHOME, RVER, RVERSION, RUSER from python to
  the _rpy module using environment variables. This avoids the need to
  have duplicate C code to obtain these values, and makes things both more
  maintainable and more robust.
