[ADD] pad: new etherpad plugin to remove autofocus

In the form views where the pads are used, Etherpad-lite automatically
focus on the pad content, even if the user has already started to type
into another field.

This behavior is quite annoying for "quick changes", so we provide a
(very tiny) plugin for Etherpad-lite that will prevent this autofocus.

Detailed installation instructions are also included.
