add dirty trick for readline import on OSX...

add dirty trick for readline import on OSX also made the libedit warning extremely loud, so people don't miss it. We still get reports of people never having noticed the warning, and getting confused when readline is broken on OSX. The reason for the dirty trick: pip installs to site-packages by default, but site-packages dirs always come *after* lib-dynload (and extras, etc.), which is where the system readline is installed. That means that a non-setuptools install (pip or setup.py install) *cannot* override any package that ships with OSX, including: numpy, readline, twisted, pyobjc without installing to a non-standard path (not even user site-packages via `--user`). The method for the dirty trick: 1. remove lib-dynload from sys.path before trying to import readline the first time 2. after import, restore lib-dynload to its place in sys.path 3. if import failed without lib-dynload, try it one more time

      """Config file for 'doctest' profile.

      This profile modifies the prompts to be the standard Python ones, so that you

      can generate easily doctests from an IPython session.

      But more importantly, it enables pasting of code with '>>>' prompts and

      arbitrary initial whitespace, as is typical of doctests in reST files and

      docstrings.  This allows you to easily re-run existing doctests and iteratively

      work on them as part of your development workflow.

      The exception mode is also set to 'plain' so the generated exceptions are as

      similar as possible to the default Python ones, for inclusion in doctests."""
