Allow iframe embedding

Issue description

It should be possible to include page generated by Topincs in other web pages via an iframe. In this case, the header is ommited and only pure HTML markup is served. Initially the best idea to trigger this behavior might be via an URI parameter. It should take effect on HTML service pages only for now.

Developer comments

This is currently only available for services: the query parameter "_if" signals the use of the page in an iframe and adds the value of the parameter to the html class attribute allowing to override any style on the page.
