[PATCH] Improved TG2 paginate decorator

[chrisz]

This patch improves the TG2 paginate decorator in several ways:

• it uses the TG2 Decoration object instead of decorating the controller manually, because
  • at least inside the decorator module, we should eat our own dogfood
  • this makes it independent of the order of decorators, particularly validate (this was a problem before, you could not write paginate after validate)
• if items_per_page is changed via URL parameter, then this is now inherited to the paginate links as well (before the setting was lost when clicking on a paginate link)
• you can now set an upper limit to the items_per_page parameter when passed via the URL (as it was possible in TG1)

Note that even though the paginate decorator removes the page key from the params, the validate decorator mixes it back again. I think this is a problem of the tg.controllers module, not a problem of the paginate decorator (see #2303).

This has been applied to 2.1 trunk, and I don't think we should apply it to 2.0 trunk. Let's leave 2.0 where it is.

Right, I actually meant this to go into 2.1 since 2.0 was in feature freeze already.
