Kill trailing whitespace

Minor cleanup with my regular workhorse

    alias find-kill-trailing-whitespace='find . -path ./.git -prune -o \( -name "*.js" -o -name "*.php" -o -name "*.css" \) -exec sed -i "s/ *$//" {} \;'

It would be awesome if the theme (or author) would drop tabs in favor of spaces (:set expandtab ftw!), as well, but I'm not counting on it :)
