toaster: make layouts consistent

toaster: make layouts consistent

The layer details page should have the same layout as all
other detail pages (recipes, packages). For this to happen,
the basebuilddetailpage.html and baseprojectpage.html
templates should use the same layout, and so should the
layerdetails.html and recipe.html templates.

This patch also capitalises the string 'All layers' in the
breadcrumb of layerdetails.html as all other breadcrumb elements.
