I think the `qunit` task should at least move to `support/client/Rakefile` as the `test` task.

Without doing anything else, it could be invoked as `rake support-client:test`. But since that's ugly and it doesn't have a `desc`, what if we add `task "client:test" => "support-client:test"` (paraphrasing) to the top-level `Rakefile` as a work-around?

I agree about saving the rest for a separate Redmine task.
