During the migration of docs to the eo file the group name changed to have a
Elm_ prefix which resulted in our docs not including this group and not showing
any of the docs in there. Switching to the new name fixes this.
Having this prefix makes sense especially as we are now merging elm into efl.
@fix
Fixes T3109
This patches introduces a new API that will make the Dayselector more
flexible. Before this patch the only way that the week this was being shown
was according to the '%a' format type from the strftime() function,
However the user may want to abbreviate using another criterion. This patch
will allow the user to do that.
