Allow shooting from rooftops

[Pollux]

We discussed this at length during the rule overhaul and decided to only ban combat on rooftops but allow other uses. Many rooftops would provide an unfair advantage and lead to people accidently head glitching on sloped surfaces. It's much better to have a blanket ban in this scenario and that is what we've done. Our new doomforting rules are stricter than ever to allow for fair gameplay, this would be a step backwards in that regard.

Denied, already discussed.
