The list of resources should be grouped by resource type

[amcewen]

When you're choosing what you want to book you should see all of the resources of the same type grouped together.

Should we have a separate page to choose the type first?

I've made a start by returning the resource type from the resources endpoint and showing that in the UI. I'll try to add some fields to resource type to fill out this page and add the grouping as mentioned.
