Navigation should automatically reflect the currently active page

Related to #48 and #46

Navigation items and menus should reflect the current page that is open. Whether that is through a Handlebars conditional (eg. {{#if isActive}}) or native nodejs solution before compiling the template. The latter would probably be best, to reduce the amount of markup and logic needed to write a template file.

with this npm handlebars-helpers package we would get access to lot of helpers quickly

Thanks for the suggestion.
