This thing is used by only 2 EO APIs that are marked as @beta. I wonder
if the @beta tag or the ptr() expression made it work for eolian,
because it simply wasn't defined in EO.
I'm renaming it just so that it's more consistent with the new names
used by atspi (and EO API in general).
Summary:
This calendar widget will support basic functionality of calendar.
I've separated this widget from elm_calendar since elm_calendar had
lots of unuseful things inside.
