Subject: [PATCH] edje_embryo: add function to know swallow has object

Summary:
Using edc script, there is no way to know evas object is set on swallow part or not.
So, to know that, some elm widget send signal and save some information to edc variables when object is set on swallow part.
I think it is helpful to make better edc script.
