Observers should start level zoomed out

[Simon]

Split off from: Multiplayer Quality of Life, renamed to New observers should watch game in progress

Observers should have the level maximum zoomed out by default to have a good overview what is going on. Else the observers have to zoom manually, which can wear one out especially with short matches.

Good idea, observers need good experience without any input.

Easy change to choose the initial zoom based on whether we're observing or playing. I'll look into this.

This will be fixed in 0.9.29. Observers will start zoomed out to see the entire map.
