Give no renown for kill in SCs

[dasparkylad]

Basically this idea comes from the fact that even with massively reduced renown gains people will STILL hold onto the objective to farm kills. Clearly massively reducing the amount of renown isn't enough for people to figure out they should be winning the scenario instead, as seeing a purple number makes them want to just keep getting more, regardless of how small it is.

So, the only obvious next step is just make it so you don't get ANY renown at all for kills in scenarios. Not seeing any purple number on kills might finally get people to realise that they should be focusing on the actual objective instead.
