Subject: 	* edje: fix signal comming from aliased part.
X-Git-Tag: submit/trunk/20120815.180907~840
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8114e4013ef111f26ddd75a9cebb992c14235eda;p=profile%2Fivi%2Fedje.git

	* edje: fix signal comming from aliased part.

	I needed to bump minor file format version, but it will only
	change behaviour for people using alias for part and they
	couldn't use the signal emitted by them.
