This issue is to improve the organization of the PyPI section of the Distutils documentation, now that the information has been combined into one page.

A patch is attached.

Improvements include:

(1) Creating a section for command options common to both register and upload.  Previously, this information was confined to the upload section, even though the information was applicable to both commands.
(2) Separating general information about PyPI (e.g. PyPI user permissions and the web interface) from the information about Distutils command usage.
(3) Consolidating information about the .pypirc file in the .pypirc section.  Previously, some of the .pypirc information was spread throughout the upload section, even though the information is equally applicable to the register command.
