Some way to specify rules per file path pattern

[mprokopowicz]

I've following project structure:

- root/
--- component/
------ component.js
------ component.test.js

component.js is some front-end script, component.test.js is a mocha test.
I need different globals in component and component.test and a few different rules (Like disabling no-unused-expressions in test, because of mochas expect(rejectedSpy).to.have.not.been.called;

For now, I end up with putting all this exceptions in comments at the beginning of test file:

/*eslint-env mocha */
/* eslint strict: [2, "global"], no-unused-expressions: [0]*/

but it would be great to have one place for this.

This is not supported yet, but was already mentioned in the ESLint 2.0 wishlist.
