Add "easy_install" script that downloads distutils source (or .egg files)

and builds and installs them as eggs, with support for managing .pth files.
Built distributions are installed in individual subdirectories, so you can
either add the directory to a .pth (automatically done by default), or you
can use pkg_resources.require() to manage your dependencies explicitly.
Because each distribution is in its own directory (or .egg file),
uninstallation and clean upgrades are trivial, without the aid of any sort
of package manager.
