This patch updates all usages of {% querystring_with %} to
{% querystring %} from /r/9712/. This has the benefit
of allowing us to specify multiple query parameters and redirect users
to page 1 of a datagrid view when changing filters (such as "Show
Closed" changing to "Hide Closed").

Ran unit tests.
