Template are not html5 compatible, duplicating part of pages
Our template are not (all) HTML5 compatible, which blocks some use of Lift with modules.
This is an architecture problem because for now, the end user is not impacted by that, but it is blocking some other work.
The main problem is with "common-layout", because depending how the include is done, all the included body is duplicated.
More over, the automatic head merge doesn't work anymore, and included part should use "head_merge" tag.
