Use data and shortcodes

Created by: ericpoirier

We should be using data and shortcodes for everything that is considered a "component".

For example, meeting_minutes, news, members logos, testimonials, events. They can all have a single data file and a shortcode so that we can add them to a markdown file easily.

We can create a data file for other components such as the footer and footer prefix but we need to create partials for them since they need to be displayed in their separate content containers.
