Subject: [PATCH] add ep_headings option to etherpad install

Make it possible to optionally install ep_headings on an etherpad
environment. This makes it easy to enable this on some environments,
but not all. Default to 'false', but set 'true' for etherpad_dev.

With summit coming up, it would be nice to have ep_headings in the
etherpads, makes them a lot easier to read.

fix puppet lint issue with all the equals signs not lining up.
