this is based on the changes for vim and basically was just switching
the foreground and background colors.
Emacs doesn't support a light/dark variation by default with themes so we have to make a special variation for this.
Maybe this is more aptly named "-invert"? I'll leave it as "-light" unless @neil477 has any suggestions.
add a -light variation for emacs
I think this is a good solution. Should probably rename the original to dark so it follows the same system as some other templates such as the TextMate one.
