Create filename and version for boexfi

Fixes broken front page URL on cdnjs.com - initial commit
(https://github.com/cdnjs/cdnjs/commit/a0eb59121afc80147c3360947b37d29af
9a573c0) managed to sneak through without a filename or version. Made
version semver-friendly - duplicated `1.0` folder to maintain backwards
compatibility. Can’t find any evidence of popularity.
