Version refresh of the RemotePi Board with ext. IR and LED and new optional external pushbutton

To be able to provide an often requested feature, we have just released a new PCB version of the RemotePi Board for Pi 3, Pi 2 and B+ with the external IR and LED... The new version has a connector socket for an optional external pushbutton on board ! This external pushbutton can be useful for projects where the RemotePi Board is mounted inside a custom case without exposing the default internal pushbutton.
