Publish all projects in Project Online using PowerShell

I was looking for a PowerShell script to publish all projects in a Project Online instance but surprisingly (or due to lack of correct google terms) couldn’t find one.

So I ended up writing one myself and uploading it on TechNet for rest of the world. You can directly download the script from this link
