Merging in ipython-ipython1b branch. This branch was used to merge in the docs from ipython1-dev, as well as the stuff from the ipython1-sconfig branch. In addition to simply merging the docs from ipython1-dev, I have completely reorganized the docs to make the easier to read and write.

Fixing minor typo in setup.py

Fixed setupbase.py and MANIFEST.in to reflect all the changes to docs. Currently, the full tree of our rst docs are not included in the data_files. Not sure if/how we want to handle that. It was easy when we had a single file documentation, but not we have a full directory hierarchy full of rst files.

Massive reorganization of the IPython documentation. It is now ready to be hacked on by users. Overall the transition to Sphinx is great. BUT, we have lots of broken links in the docs. Developers need to become familiar with how Sphinx handles links.

More moving around doc files.

Beginning to organize the rst documentation.

Merging changes from trunk: fix in setupbase.py (ipython->IPython) and missing __init__.py files.

Fixing a few small bugs in the setup.py scripts. In setupbase.py, in find_scripts, ipython was spelled as lowercase. This didn't cause a problem on OS X as it is case insensitive. But on Linux, it crashed. Now ipython is spelled properly as "IPython". Also, kernel/config/tests and UserConfig were missing their __init__.py files. These have been added.

Merge sconfig branch.

Creating subdirs in docs/source for each subpackage documentation.
