Also prefix with widget.
I want to rename this as child rather than sub. It's inconsistent with
the other parent/child hierarchies. Anyway the various hierarchies are
confusing, so let's keep this name :)
Ref T5363
Summary: Added new flip mode called ELM_FLIP_CROSS_FADE, which causes one content to fade in while the other fades out. Updated test_flip.c program to include a button for testing the new flip mode.
Test Plan: Run the elementary_test program, and open the Flip test. There is a new button labelled "9" that will activate the new cross-fade flip mode.
