Motivation / Problem

(part of commit message)

Nobody really paid attention to the lobby window, and it completely
missed its purpose. Most people don't even wait for companies to
show up, but just hit "New Company".
This in turn means people create a lot of unneeded companies, while
they "just want to watch the game" or join another company.

Description

(part of commit message)

Instead, "Join Game" now just joins the game as spectators.

A future PR will address the gap that now exists between: I joined a server, now how to start playing?

Can't the server side be simplified as well? Practically not implementing Receive_CLIENT_COMPANY_INFO (and letting tcp_game's implementation take over) would be possible since the lobby should never be shown without going through the game list which prevents connecting to a server with the wrong version, right?
Alternatively sending SERVER_COMPANY_INFO (SendCompanyInfo) gets heavily simplified by just sending a packet with that type and a new version number and a false boolean. Then the protocol is not closing the client's connection, but the client gets nothing except an unexpected version which is to be expected when you send a newer version. Although that might ofcourse cause whining from some people that you cannot acquire that information anymore, but alas... they should be using the admin protocol instead I guess.
I can imagine postponing this can of worms to a separate PR though.

As with the other comment, these packets are part of the "we never going to change this" group. I am in no mood to look into that any further :P So possibly you are right .. but yeah, not for this PR :)

Edit: I created #9475 to address this.

To give that change a bit more visibility, I did that in #9475 .
