Bots often have the habit of trying a next page, even if there isn't one.
Thus, using CurrentPage < TotalPages, prevents from unwanted next-links being shown.
In some circumstances a custom generated list will already only contain
the items for the current page. The automatic limiting will then limit
the already limited list, breaking pagination. This allows you to disable
automatic limiting so all items are shown regardless of the current page.
API CHANGE: Deprecated SS_List::getRange() in favour of SS_Limitable::limit().
API CHANGE: Introduce SS_Limitable::limit($limit, $offset = 0) as the only modern way of specifying limits; deprecate all others.
API CHANGE: Removed pagination related methods from DataObjectSet and implemented them on PaginatedList.
API CHANGE: Removed DataObjectSet::parseQueryLimit(), this is now implemented as PaginatedList::setPaginationFromQuery().
API CHANGE: Deprecated DataObjectSet::TotalItems in favour of Count().
ENHANCEMENT: Added FirstLink and LastLink to PaginatedList.
MINOR: Updated documentation, and added a how-to on paginating items.
