.vimrc needs comments

[John Whitlock]

You need to say why you use the lines in .vimrc.

[Josh Mize]

I don't actually use that .vimrc very often anymore, and so I don't think I'll be spending any time on adding comments. Most of my time these days is spent within evil mode spacemacs, and the customizations in https://github.com/jgmize/dotfiles/blob/master/.spacemacs are better commented :)
