Title: Windows user: plugin.bat to install contrib repository

Here is my stab at translating the plugin shell script into a working solution for windows users.
Hoping it could be useful to you as a v1 script
It's my first time medling with batch, even a little of powershell was needed.
So if any real powershell user pass by, a lot could be improved I suppose :P
