Alright! Got some more protocol in there:
Commander selection and connected states are menu-ed up. Game knows how to watch the scenario's state and flip between inactive and active modes. Ready/NotReady works. Player list is shown with ready state. First version of minimap is in there, fixed the healthbars.
Not much, but the old client's guts are making their way across.

It's good practice making them. :) Maybe next week I'll be daring and include... SOUND....
Er, not that there's sound in the game yet; someday.
