[firefox] Make it possible to stow firefox configuration

- Put ‘userChrome.css’ into the ‘src/’ directory and have stow ignore any such
  directory.

- Dynamically find the name of the default firefox profile.

- In case the firefox profile can't be found, output some messages stating such.

- Update the ‘userChrome.css’ as used by Firefox.
