After install, some of the modules files are overwritten (README.md, .gitignore)

[dpolivy]

By downloading and unzipping the CLDR archives into the module root directory, any files contained in the module ZIP files that collide with this module's files will cause this module's versions to be overwritten. Additionally, extra files from the module packaging process are now 'leaking' into the root directory for this module.

The install process should be better about ensuring that only the CLDR json files are installed, and/or use a subdirectory to better separate the files.
