Add QHttpServer-based mock server

This should allow for creating tests more easily than the python-based server, since we can poke at it from C++ code.
The idea is that each test creates the things it needs (rooms in a certain state, etc) programmatically instead of through
the json files we use for the other tests. This allows us to adapt the test data to each test as needed, without having to copy it around a lot.
