Observers no longer lag the game for players. There is still some time
to serialise the game when sending it to a joining observer, and
depending on the chosen 'max lag' the game may stop while observers
sufficiently catch up, but this impact too is reduced.
- Make the NetServerTurnManager ignore players marked as 'observers' for
the purpose of ending a turn, effectively making it possible for
observers to lag without it affecting the players in any way.
- Add a config option (network.observermaxlag) that specifies how many
turns behind the live game observers are allowed to be. Default to 10
turns, or 2 seconds, to keep them 'largely live'.
- The controller is not treated as an observer.
- Implement a simple UI to show this delay & allow the game to speed up
automatically to try and catch up. This can be deactivated via
network.autocatchup.
- Move network options to the renamed 'Network / Lobby' options page.
- Do not debug_warn/crash when receiving commands from the past -
instead warn and carry on, to avoid DOS and "coop play" issues.

This was SVN commit r25156.
To hide network latency, MP turns send commands not for the next turn
but N turns after that (introduced in c684c211a2).
Further, MP turn length was increased to 500ms compared to 200ms SP
turns (introduced in 6a15b78c98).
Unfortunately, increasing MP turn length has negative consequences:
- makes pathfinding/unit motion much worse & unit behaviour worse in
general.
- makes the game more 'lag-spikey', since computations are done less
often, but thus then can take more time.
This diff essentially reverts 6a15b78c98, instead increasing
COMMAND_DELAY from 2 to 4 in MP. This:
- Reduces the 'inherent command lag' in MP from 1000ms to 800ms
- Increases the lag range at which MP will run smoothtly from 500ms to
600ms
- makes SP and MP turns behave identically again, removing the
hindrances described above.
As a side effect, single-player was not actually using COMMAND_DELAY,
this is now done (can be used to simulate MP command lag).

This cleans up many un-necessary header includes, either simply
providing nothing or forward declarations in their place.
No major compilation time change here, though this does reduce depencies
in some headers.
Also fix up old MacOS STL-include fixes that are no longer relevant.

Thus remove the peculiarity to broadcast to clients that are in the
gamesetup, loading screen or ingame, but not rejoining ones.
Fix "unknown player" errors in the GUI by broadcasting player
assignments to rejoining players too. Fixes#4036.
