Merge branch 'python' into namespaced-python

I moved the new COPYING and README.md into setup/windows-installer/ so
they're namespaced along with the script itself.

* python:
  Replace 'Anaconda CE' -> 'Anaconda'
  Mention that R should be installed before running our installer
  swc-windows-installer.py: Add --version and start with 0.1
  swc-windows-installer.py: Search ProgramW6432 and ProgramFiles(x86)
  swc-windows-installer.py: Add missing space to 'c:\ProgramFiles'
  swc-windows-installer.py: Set default logging level to INFO
  Fix 'Add' -> 'Adds' to match 'The script' lead-in
  README.md: Copy the docstring into a README
  swc-windows-installer.py: Fix 'swc_windows_installer.py' -> hyphens
  swc-windows-installer.py: Change '~/nano.rc' to 'a ~/nano.rc'
  swc-windows-installer.py: Canonical SQLite capitalization
  COPYING: Add the full text of the MIT license
