Main page update

[OAGr]

A new card layout for spaces. This is possible and more reasonable now that we have more space images. This impacts the main search page and the user pages, but does not yet impact that organizational pages.

Can you do the imports for consistency with how I've been ordering them? Like this:

import React from 'react'

import Icon from 'react-fa'

import * as navigationActions from 'gModules/navigation/actions'

import * as Space from 'gEngine/space'
import * as User from 'gEngine/user'

import {formatDescription, formatDate} from 'gComponents/spaces/shared'

import arrowsVisibleImage from '../../../assets/metric-icons/blue/arrows-visible.png'

import './style.css'

Ordered by sections like this, new lines separating sections:
- React
- Redux
- NPM modules
- Internal components
- Internal selectors
- Internal actions
- Engine
- Internal libs
- servers
- Images
- Stylesheets
