Layouts Refactoring + Utilities

[cycomachead]

We have a lot of layouts which are:

• heading + grid of items
• a collection of carousels

We need a page type which has:

• title / locale string
• items to display
• grid parameters

All 3 could easily be defined in the controller. We could keep one lua template per route and make this a large partial, which might be little cleaner

A second page/large partial for a collection of collections.

Common Helpers

• font awesome function
• we should have a set title yield in the main layout
• probably a helper to translate "items per page" to col-X classes
