Library filtering and display enhancements (#214)
* Implement infinite scrolling and paging (selected via preference) (closes #202) * Display game counts on more filter types (closes #194) * Make game counts larger (closes #194) * Include age groups in filtering (closes #200) * Add sorting options (closes #145)
