edje/edje_entry : By this commit, preediting texts will be shown

differently. When inputting Korean text, preediting text will be shown
as selected. When inputting Japaneses text, preediting text will be
shown with underline. (Sometimes shown as selected for changing whole
preediting text to another text)
