Wreck 1.2

I have made a major update to Wreck:

• Includes a section on play and refereeing advice.
• Includes an overview of the system and setting.
• Corrected several typographic errors.
• Higher resolution graphics added to cover.
• Fixed the "Speech" character description table.
• Added a 3-page rules summary at the end with an abbreviated discussion of the major rules.
• Put a placeholder in for a character sheet.
