addImagesAndDescriptions: finished config file, edit template to fit new...

## Description
Descriptions are now coming from the resources SDK instead of being hard coded into the `config.json` file.

Added the new images and also added a `max-width` of `450px` on the body since this isn't responsive yet and the images don't look pretty when scaled up to a larger browser size.

## Stuff that will break this
If you change the room names in the google account, you will have to also change the name in the `config.json` file under the name key for that room. The name is how we are mapping the image to the room, so changing the room name will result in the app not being able to find the correct image when the map icon is clicked.
