Looks nice. Special kudos for managing much of the wp-config though the built in config constants.
Only thing I don't like is the renaming of the root `wp-config` folder to `app`. I'd much rather have the app reflect the underlying wordpress conventions than to change it to look like something else. Yeah, consistency, but boo for barrier of entry or having to remember that `app` == `wp-config` when not everything we get to work on will get to use the shiny fandangled tool.
