made the client window size immutable.
added some dev notes to a file.
renamed Lobby.healthcheck to Lobby.purge, which makes more sense.

+• there's, at most, two players waiting in the lobby at a given time.

+it makes no sense to allocate more than two seats since the threadsim

+will consume them whenever they are ready to join the party.  i'm

+thinking of using channels to synchronize the two threads, so

+threadsim doesn't loop doing nothing (but sleeping) until at least a

+couple of players join.

+

+• the integrator has to operate with vectors and the different objects

+in the universe, some of which may require their own governing laws.

+

+• think of a way to pack the bullets efficiently.  will they be part

+of the global state broadcast?  what does the client need to know to

+render and manage them?

+

+• it could be beneficial to do dynamics in the client as well, which

+means sending more data, and probably require a tighter sync, but a

+smoother user experience.
