Overdrive

First Megastreak: Overdrive
Activated at a streak of 10 kills, the player gets a boost to their gold and xp gains, but starts taking more and more damage the higher the streak is.

Added a "chat":
You can now see the exact amount of gold and xp earned a kill, and when your mega activates.

Planned:
I still want to work on prestiging soon, but I would like to have the game be a bit more interesting before then.
Contracts minor event could do the trick
