v1.0.0

ListView refactor:

• Refactor existing ListView component (an adaptation of React Native's now deprecated ListView) to work with FlatList and SectionList under the hood
• New hasFeaturedItem & renderFeaturedItem() props used to render a specific item as the featured item, by default, if no specific item is provided, the first item from the overall data will be used as the featured item
• New sections prop used to render specified sections with section headers (either the default one provided by the UI toolkit, or a specific one provided by renderSectionHeader())
