Title: [#1325] Add ability to remove listeners by function equality

Fixes Lighthouse ticket #[1325](https://webmademovies.lighthouseapp.com/projects/63272-popcornjs/tickets/1325-off-should-unlisten-by-function-equality-not-by-name).

Modifies unlisten() function (aliased as off()) to allow passing a function in, and deleting matching functions.
