Updated the change log.

xcg/oemetasl is now obsolete. We are going to prefer mixins instead. As we no
longer have any other metaclass than this one, the metaclass inheritance is no
longer needed.

Changed method to allow having readonly in a view on analytic dimensions placeholder so that all analytic fields will get readonly too.

- "Structure" -> "Structures"

Can now use <div class="oe_analytic" prefix="prefix" /> in order to place every remaining field associated with a structure in the view. Added a README.

Also added a config check on module load.
