Title: .vimrc: respect modeline by default

`:help modeline`

This feature is very useful for enforcing consistent whitespacing (tab vs space), indenting (4 vs 2 spaces) and many others.

By enabling this setting, users can opt into modeline by commenting their files. If vim does not detect anything in the first 4 lines of any file, it will simple ignore and use default settings as specificed by the .vimrc file.
