Add field for Contact Info on About PECE Page

[lindsaypoirier]

There should be a new field on the About PECE content type where the site admin can list contact info for the instance. This field should include a title and an email address. Let's also make this a repeater field for the corner case where someone would want multiple people listed as potential contacts. The field should appear on the about page in the right sidebar with the title hyperlinked to the email.
