Strip trailing whitespace every time you save a file in Sublime Text

Wanna get make all your files use spaces for tabs consistently and eliminate trailing whitespace every time you save in sublime? Put this in your user preferences:

{
  "font_size": 13.0,
  "tab_size": 2,
  "translate_tabs_to_spaces": true,
  "trim_automatic_white_space": true,
  "trim_trailing_white_space_on_save": true,
  "use_tab_stops": true
}

I absolutely hate trailing whitespace in any of my code. I used to use a plugin that eliminates it when you hit a predefined keystroke, but this is much more convenient.
