user template broken

looking at #1103 it seems the user templates have issues

basically the edit user button is not showing.  It looks like `user/read_base.html` is the problem as it does not include the button block.  I'm not sure if this is a minor oversight or a bigger templating issue that makes it hard to consistently add template buttons.

This affects 2.1 and master and is a regression and needs backporting.
