possible fix for deprecating config.action_view.debug_rjs=

I can write tests for this as needed

I see your point, but I think such a message could be confusing. People using RJS today will be using that configuration option in 3.1. It is not exactly deprecated.

The switch to jQuery and the extraction of Prototype and RJS are important known changes in 3.1. You need to be aware of them if you're upgrading an application. In particular, if you're not using Prototype you need to remove that line.

Thanks for the pull request anyway.

I was basically trying to solve the issue brought up in #2098. The wording of the deprecation can change but it still seems to be an outstanding issue.

Ah, I see. Then it makes sense that this is coherent, I'll reopen.

I checked it, and the warning actually gets printed. That happens in 3-0-stable. As the message says everything related to RJS is removed from 3.1, so I don't really see this message in 3-1-stable.
