This simply moves the codeEditor folder to the components directory. `codeEditor.jsx` simply builds a component which is then used elsewhere, and isn't shared between client and server, so it should be in the client directory.
Arguably it could go in `client/homebrew/editor` but I think the `/homebrew/` folder should be eliminated down the line and it's contents just re-sorted.
When working on the editor right now it's a pain to switch between `shared` and `client` hunting for the right file.
