Applying post to model

With model:get_post(post) and autogenerated forms now models are able to
catch attributes from POST.
Default layout and access from rendered pages to global environment

This default layout is powered by twitter bootstrap. To add new layouts, add
a new folder under /layouts and change default layout name on /conf/conf.lua.
page:render() will replace {{content}} tag with the requested .lp. If you
want different pages to use different layouts you can set page.layout with a
different value on controller before rendering.
