Change to server-side pagination for Sibling Albums and Sub Dirs

- Only paritial pagination, first X, then showAll - Default is 40 for subDirs and sibling albums each - showAll parameter causes page refresh with entirely new list TODO/Future improvements include: - Finer grain pagination - Pagination done at the database level - Seamless refresh with JS - Unify all pagination uses across the site Signed-off-by: Andrew DeMaria <lostonamountain@gmail.com>
