make link_to_navigation more generic and reuse it
Use link_to_navigation for all important navigation items. It creates a link in a list item for use with bootstrap. It supports an :active flag and an :icon option in the html_options now. It also translates the label. This way it can be used in a lot of places as the generic navigation link.
