LayoutRootPath breaks content elements

[RauchF]

Because the default templates of Fluid Styled Content all use the layout "Default", the new setting for LayoutRootPaths in eb6ff43 causes our "Default" page layout to be used for content elements.

This breaks many things including but not limited to headlines.

The only solutions I see are either setting a new LayoutRootPath for content elements or renaming the page layout. The latter option however might lead to more future confusion.

As mentioned in my comment on the commit I'll probably revert this again, or introduce a more consistent split of Layout, Partial, and Template folders to {Templates,Layouts,Partials}/{Page,Content} so we can avoid having to restructure things wildly
