So I've started playing Hedgewars with a few friends of mine, and we play quite often, but often one of us needs to leave the keyboard for a while, and I figured it'd be neat with some kind of "away" mode.
It'd be really simple to implement, I'm thinking something like "automatically skip turn" (e.g. see if away mode is active at beginning of turn, if it is just automatically skip the turn as if the user manually used the 'skip turn' action).

Yes, the idea is pretty simple, but I think it would be neat; in the end it's just the same as if I'd manually click the skip turn button, so it shouldn't affect game balance.
