New minor version (v1.1)

I've used some feedback from Cody at Nightbird Games (check out their great solo game, The Ferryman, if you have not already done so) to make some valuable adjustments to Load Up!

Nothing major, but if you've download v1.0, it would be worth grabbing this version instead. Key points:

• Improved clarity of rules
• Adjustments to some events
• Slight increase in difficulty related to Risk
  • When facing final zombies, they now number 'Risk+2' instead of just 'Risk'
  • A couple of events generate more risk.

Thanks to Cody and to you for downloading my game. I hope you're enjoying it!
