[postphotos]

part of the components listed in #12.

As requested (and detailed) by @miina here.

Mockups are available here:

• https://www.figma.com/file/L14jTE7iNGOE7DH57Ro7ncyu/Travel-Theme
• https://ampstart-iframes.firebaseapp.com/templates/travel/travel.amp

Some notes from #9 apply here:

Would be used for the display post (next to "Discover Adventures"), for Top Adventures Near You; Would have controls to choose: How many posts to show; Which category posts to show; How to sort (e.g. by meta value X); Layout / or which fields to display. For example for the post next to "Discover Adventures" you could choose layout A; 1 post; category "Food", for the the Top Adventures Near You" could choose layout B; 3 posts; category "Adventure"; sort by meta value Review; Question: Does this make sense for these two sections from the editor's point of view?

Category/taxonomy list block: Would be used for "Browse by activity" and "Featured destinations"; Would have option to choose which fields to display (e.g. meta value such as icon / background image; count of posts Option to choose how many categories to display; Perhaps option to filter by "featured" Option to sort by ... ?
