Being annoyed by different types of eina critical macros - CRI, CRIT,
CRITICAL -, I concluded to unify them to one. Discussed on IRC and
finally, CRI was chosen to meet the consistency with other macros -
ERR, WRN, INF, DBG - in terms of the number of characters.
If there is any missing bits, please let me know.
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.
