Move the server-side rendered views out into a separate file

[eeue56]

Right now, we have files like this one - https://github.com/NoRedInk/take-home/blob/master/instance/server/Client/StartTakeHome/Views.elm which contains views which are both used with writeNode, which is the server-side rendering call, and writeElm, which sends things down with an attached Elm runtime. They should be in a separate file, so it's clear which ones are server-side rendered.
