Parent project update

- HomeFragment: When image is not yet loaded the space for it already
preserved on the screen and background is shown. This allows to avoid
view resizing
- AspectRatioImageView: added possibility to set aspect ratio explicitly
- layout/list_item_newest_photos.xml: added scaleType to the photo view
