Renamed rendering service to handlebars
- This fits more closely, as this service is to so with rendering helpers and small parts
- Whereas we want to use "rendering" for things concerned with rendering pages

// # Content Helper
// Usage: `{{content}}`, `{{content words="20"}}`, `{{content characters="256"}}`
//
// Turns content html into a safestring so that the user doesn't have to
// escape it or tell handlebars to leave it alone with a triple-brace.
//
// Shows default or custom CTA when trying to see content without access
//
// Enables tag-safe truncation of content by characters or words.
//
// Dev flag feature: In case of restricted content access for member-only posts, shows CTA box
