Auto remove trailing whitespace

Copy this in your .vimrc.local, and any trailing whitespace will be highlighted, and automatically removed when you write the file.

"highlight trailing whitespace
match ErrorMsg '\s\+$'
" kill trailing whitespaces automatically
autocmd BufWritePre * :%s/\s\+$//e

Yes, I totally stole this from someone else's vimrc on github.
