Tournament games get slightly increased death timers, slightly weaker turrets

Other modes get adjusted to compensate.

I get what Riot's trying to do, but stopping pro games from being stallfests is hurting the rest of the playerbase. Vastly different balance states between us and the pros would be a bit much, but if Riot is ever going to implement something like that, this simple change is the perfect opportunity.

tl;dr: Give us reasonable death timers and useful towers, give pro games what we have now.
