Title: Quote identifier names when --no-color is specified

The output should be `unused variable 'helper'` instead of `unused variable helper` when `--no-color` is specified. This makes the output unambiguous and more readable, and has the big advantage of making the variable name easier to parse (important for IDEs and other tools that call luacheck).

The code in `format.lua` may need refactoring.
