** [tickets:#6835] @validate decorators without if_invalid or error checking
are useless**

A URL like this /p/.../discussion/general/?limit=1&page=2x generates this error:
~~~~
Module forgediscussion.controllers.forum:102 in index view
>> limit, page, start = g.handle_paging(limit, page)
Module allura.lib.app_globals:359 in handle_paging view
>> page = max(int(page), 0)
ValueError: invalid literal for int() with base 10: '2x'
~~~~
despite having `@validate(dict(page=validators.Int(if_empty=0),` on the
controller, because all that @validate does is determine if there are errors
and sets them up on the template context for the controller/template to handle.
On form submissions, the form is normally set up to show error messages, but
if that's not set up nothing happens - e.g. handling GET url parameters.
We should have if_invalid=0 on the validator.
