Move codeEditor to components directory

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.

client/components/codeEditor/fold-css.js
