Version 0.7 - just some bug fixes

This is just a small iteration to fix some erros in the rules text from v 0.6.

• Second Wind (Spectacle Card) updated to work like the Center action.
• Bits & Bobs : fixed the number of needed dice for play.
• "test dice" renamed to "skill dice".
• Added the "Skill & Strain" header to the appropriate rules section.
• Added the exact procedure for handling the Strain token on a Seeker card.
• Removed the unimplemented Down effect.

As a sidenote, I finally got around crafting a somewhat presentable paper prototype :)
