including a routhio.html section in packmaker.yml causes an exception on build-routhio
It appears the code to copy of the content defined in the routhio.html section of a packdef to a build is using the same copy_files() code that is used for the general files content. However, the general files content now is capable of using jinja2 templates there and this code is looking for attributes in the location definition about templates. The routhio.html definition doesn't have such attributes and therefore the code is raising exception.
