Content types not sorted correctly on node/add page

The list of content types on the "Content types" page at admin/structure/types is sorted by weight and then label. The list on the "Add content" page at node/add isn't sorted at all, so it comes out by machine name, which can lead to unexpected results. (Suppose, for example, you rename "Basic page" to just "Page". If you also have a "Blog post" content type, "Page" will counter-intuitively sort above it.) Both pages should use the same logic. It's a trivial fix. Patch to follow.
