VIM: Adds bindings to default to "very magic" searching

By default, vim's reg-ex matching is weird. For example:

> * is special when not escaped but…
> + is special when escaped
> \{x,y} (escaping only the opening bracket) works but…
> You have to use \( \) (escape both parens)
> [] is special when both are unescaped
