* Rename PaginationState.timelineEndReached to PaginationState.endReached. * Rename PaginationState to TimelinePaginationState. Also renames PaginationStatus to PaginationState so that a TimelinePaginationState consists of the forward and backward pagination states. * Add the empty state to SpaceScreen. Only has 1 of the 2 buttons for now.
