Rule proposal: relative path start with "./"

[gajus]

import './test.js';
import './../test.js';
import '../test.js';

This is an OCD thing, but I'd like all relative paths to start with './'. I dislike the inconsistent use:

import './../test.js';
import '../test.js';

I will submit a PR if accepted.
