RFC: organizing the wiki

[fu]

I started with a desire to document how to submit changes to a release branch, and somehow ended up trying to figure out how we could organize the wiki to make it easy for us to figure out what we have and what we need.

Please read and comment on my entry in dw-wiki. I'm locking comments here so we can centralize all discussion in one place.

Renaming Apache2::Request $r

[fu]

I keep tripping over $r which is from DW::Request->get, and is a DW::Request object $r which is an actual Apache2::RequestRec object -- the two are used in similar contexts and often have similarly named methods, but then you'll run into a method which behaves a a bit differently from one to the other and spend two hours debugging a completely unrelated thing.

We're trying to move away from Apache2::RequestRec objects and converting them into DW::Request where needed. How about we rename the old $r to $apache_r, and keep the new $r the same, so it's obvious at a glance which is which?

ETA: I've gone ahead and done just that for https://github.com/dreamwidth/dw-free/pull/211
