CD-18 Expose aws box url

This creates a link to the aws box that's created during ci. Right now it uses the users github icon as the button, but this can be changed later with a real icon. (I didn't want to take a stab at art)
Yes, there will be a pattern defined and documented by Strider. With that I can go to placelocal project or any other project and put something like `echo "LINK:http://whatever.domain]"` in the integration script and have a link show up in Strider. Developer is not a "dependency", developer is a customer.

I dislike this change as is mainly because it doesn't improve strider as a unit. It's sort of wash because the feature comes with a bit of engineering debt and unanswered question about where to go from here. It should be noted that nowhere in strider codebase did we special case for PlaceLocal project. It contradicts the design of the tool.

But again, I like the idea and would use this. What are the technical objections to altering the code exactly?
