Renaming a package, again

There is a problem with packages containing dots in their name. At least in ST3.
See: https://github.com/michfield/sublime-strapdown-preview/issues/1

I assume you could sanitize package names, but it's easier for everybody just to rename my package, again :(

Thanks
