Changes

This PR fixes two issues with the website.

1. In the navbar under the "about" dropdown, the "open source" link does not work. This is because ActiveLink.js passes an external link to the Link element, which is meant to only work for internal links. See ActiveLink.js for the specific change.
2. On the officers page, the officer cards are not responsive in Firefox browser specifically (each card is on its own line). See committees.scss for the specific change.
