Initial work towards refactoring the setup.py scripts to accept the new ipython1 packages

that have been merged.  I am also bringing in a new way for checking dependencies at
build time that is simple, but really helpful now that we have lots of optional
dependencies.

 IPython provides a replacement for the interactive Python interpreter with
 extra functionality.
 
 Main features:
 
  * Comprehensive object introspection.
 
  * Input history, persistent across sessions.
 
  * Caching of output results during a session with automatically generated
    references.
 
  * Readline based name completion.
 
  * Extensible system of 'magic' commands for controlling the environment and
    performing many tasks related either to IPython or the operating system.
 
  * Configuration system with easy switching between different setups (simpler
    than changing $PYTHONSTARTUP environment variables every time).
 
  * Session logging and reloading.
 
  * Extensible syntax processing for special purpose situations.
 
  * Access to the system shell with user-extensible alias system.
 
  * Easily embeddable in other Python programs.
 
  * Integrated access to the pdb debugger and the Python profiler. 
 
  The latest development version is always available at the IPython subversion
  repository_.
