bump handlebars dependency from 4.3.1 to 4.5.0 (#557)

Resolves a build warning due to incompatible versions of slf4j.

Change in HandlebarsTemplateEngine is due to a change in handlebars where they no longer shade commons text in their jar.

Exclude the nashhorn-core dependency from handlebars since it is not license compliant. It is only needed for javascript support in templates which we do not use.
