Subject: [PATCH] Add a filter by account function to contributors

This allows to filter contributors by the account entries.
For example:

```js

Contributor.filterByAccount({site: 'github.com'}); // returns all
contributors with github account
Contributor.filterByAccount({site: 'github.com', username: 'bumi'});
// returns bumi

```
