[patch] Generic view `list_detail` pagination should be one-indexed in URL

[Tom Tobin <korpios@…>]

While having the ObjectPaginator class be zero-indexed internally makes sense, having the GET variable for the current page number also be zero-indexed doesn't; one-indexed numbers are all a user should have to understand, and it's doubly confusing to be visiting a page claiming to be "3 of 4" yet have ?page=2 in the URL.

The attached patch fixes the list_detail generic view to be one-indexed, while leaving ObjectPaginator alone (i.e., zero-indexed).

(In [2426]) Fixed #1033 -- pagination in object_list generic views now use 1-indexed page numbers in the URL. Thanks, Tom Tobin.
