New Component: Pre-heading

[craigcook]

We sometimes need to show a "teaser" or "eyebrow" above a main title, usually as some kind of context-setter to introduce the title that follows it. It might indicate a page category or classification, for example.

We have a design for this component, now we need to work out the specifics and implement it. These screenshots are of a colored/pill style variant and there's also a plain text version (which should probably be the default).
