Remove chrome.coffee

Remove chrome.coffee

- Remove chrome.coffee, which added Cc, Ci and Cu globally.
- Add definitions of those in files where needed.
- Fix consistent formatting of their definitions.
- Fix consistent placement of their definitions: after reqiures. Includes
  cleaning up the requires sometimes, involving alignment.
- When fixing alignment of requires I couldn't help but to also fix
  alignments in other places.
- Trailing whitespace was also removed by my editor.
