Why are the shell scripts empty?

@brynrhodes, they aren't empty. I simply changed the permissions on those files to make them executable. The "empty file" that GitHub references is the diff because there are no changes to the file's contents. I believe you'd see the same if you simply changed a filename and not the contents. If you look at those files in this branch, you'll see the content is unchanged.

i.e. 644 -> 755 or -rw-rw-r-- -> -rwxrwxr-x

I needed to run _updatePublisher.sh and _genonce.sh to validate my changes.

Discussed with @brynrhodes out-of-band. Permissions changes to scripts need to be done at source so they aren't undone with future executions of _updatePublisher. Believe this change needs to be made in this project:
