Link to icinga pages, template modifications

The latest commit in the imoin repository brings a new feature:

Each host and each service can be clicked and opens the corresponding icinga status page for that host or service.

This feature was implemented to meet a requirement for the approval process at Mozilla. It was necessary to drop tags like <script type="text/template"></script> in favour of <template></template>. These tags are very handy - if only IE would support them. Btw. visit the polymer project, which is a new way out of the div soup into a more descriptive tagging world.
