elm_image: add a new eo property 'align' and implement related functions
previously, elm_image refered to align values set by evas_object_size_hint_align_set function to position the internal image inside an image object. size hint value is for positioning the image object inside its container object, so the previous code is inappropriate. this commit adds 'align' property for positioning the internal image.
