Write an "about" document titled "Distributing a Plaster Template"

[daviwil]

In addition to "Creating a Plaster Manifest", we'll also need an about document describing how to distribute a Plaster template via the PowerShell Gallery.

I created a project for containing Plaster templates named PlasterPlethora. I thought I might as well kick-start the community with this. Hopefully it can be a starter for getting us going with a way to share Plaster templates. I hope people will find it useful. I'm all ears for comments and feedback.

Kind regards.
