Implement coverage for Housing endpoints

[ixnoahlive]

Currently has implementation for the /housing/house endpoint. Creating this before the other two are properly implemented due to some issues with the way they are served. (arrays at the top level instead of the usual object structure)

Will also try to make examples for these later.

Anyone willing to try their hands at these two other endpoints are welcome to do so, and I'll hopefully try to do a little work on it myself if I can find the time.
