Selectively enable/disable comment rendering by node type

I have a need to solve the general problem stated here. More specifically, I'd like to display the comment form in a place of my choosing, rather than having it baked in to the theme $content variable by the node_show() function.

There are numerous approaches outlined in that thread, and I'm not a fan of preprocess/remove as we are then rendering everything twice and just removing it from display. I liked this solution:

Not easily doable in core, but comment_bonus_api takes over node_show and replaces it with our own. That allows us to do fun things like not render comments.

That's what the next patch does: adds an admin UI page for this module that allows for selective enabling/disabling of the comment form on a per node-type basis. Just visit the UI, uncheck the box, and our version of node_show will stop rendering your comments. It's up to you to then render them properly where you want them to go.
