Adding Common.Body.Summary template that displays a generated body excerpt

- Added body summary template
- Added an Ellipsize(int length) string extension
- Added an Excerpt(string markup, int length) HtmlHelper extension
- Added a LongestMatch method to ContentPartTemplateResult (pretty much a copy/paste from item) to get the fallback on filename functionality
- Changed the BodyDriver to try to display SummaryAdmin or Summary template variations on Body if the displayType fits
