Pajamas page titles in browser tabs

Problem

When using Pajamas in Chrome, the page title isn't reflected in the chrome tabs... making it harder to work with multiple components or areas of PJs simultaneously:

Solution

• Update chrome tabs to reflect page title.
• Format something like: Foundations: Color or Color, Foundations, Product... we want to frontload the important words for when the tabs are small and partially hide the title
