Remove bitmap caching from ScrollableImagePreview

Remove bitmap caching from ScrollableImagePreview; instead, extend the
image loader interface to proivde a cache-control option.
ScrollableImagePreview$BatchPreviewLoader requests caching only for the
first visible items as we'd like them to be displayed as fast as
possible and not be evicted by any of the remaining items.
Minor fixes inside ImagePreviewImageLoader.
ImageLoader is moved into contentpreview package.
