Remove extra newlines at the end of files

The improved linting ensured that the JavaScript sources had exactly one
newline at the end of files, but this did not apply to everything in the
repository. This change covers the remaining files.
Bump the version number for initial release

Incidentally, the existing version number should have been 0.1.0-pre.

This change also adds an empty npmignore file to avoid ignoring the
generated unicode module.
