Repackaged, moved bits back to editor.

Pacman is just going to handle getting packages onto your machine and built.
The editor can build on that and scan the installed packages for Scaled stuffs
(major and minor modes, plugins, etc. etc.). There's no especial value in
having that stuff in the package manager.
More explicit config file modeling.

After arguing with Paul about it all day, I felt the need to put my money where
my mouth was.
