Much appreciated

There's no telling how much longer KarBOOM would've taken to make if I wanted to have online working well - especially since the engine switch means it'd need to be re-implemented from scratch. But maybe one day!

My tentative post-release schedule is:

• Bugs and complaints addressed + simple new mutators
• Fix up the AI system to accommodate more interesting arena layouts + (hopefully) a couple more interesting arenas
• Re-explore online. Which could take a while, so maybe roll out some cool new arenas during that experimentation to keep people engaged.
