Updated infinite scrolling and fixed bugs

- Scrollable area now fills the rest of the viewport
- Initial page is now 50
- The next page will always be loaded upon scrolling to the bottom of a
list (with a spinner to show a search is in progress)
- Moved the "Create New" action outside of the scrolling area
Merge pull request #439 from reciprocity/feature/scroll-paging

Added infinite scrolling to LHN searches
