Publishing the premium zip file to the Intelly Website

Process for releasing an Intelly zip file:
* Create a local copy of one of the Intelly Plugin Pro versions from either the EDD branch or the WHMCS branch.
* Update the readme.txt to have the current release date.
* Zip the top level of the branch but exclude git related files such as .git and README.md.
* Within the zip file, all of the plugin files must be in a folder named: intelly-related-posts-pro
