Massively refactor

- Redefine as much as possible as `setup' forms
- Reorganize into "Setup", "Basics", and "Packages" sections
- Within each section, alphabetize sexps
- Also (mostly) alphabetize acdw- files
- (Not the ones that are almost completely others' code)
- Sidebar: Why is this not a thing in elisp!?  Should write a function
- Break karthink's thing into another library `acdw-re'
- Add a function to `acdw': `acdw/find-emacs-source'
- Should refactor that to better find the source

I think everything looks much more better now!
