More Mystcraft

This is an alpha release and should NOT be used with worlds you intend to keep. 

Added Tilt pages. These can be used with the new "Tinted Sun" page to tilt the sun's trajectory through the sky. 

Added a new "Tinted Sun" page. This page is meant to replace the default "Normal Sun" page, though you can keep both pages available. They are each just as likely to be chosen by the Mystcraft grammar filler. A Tinted Sun is very similar to a Normal Sun, but is accepts several more modifiers:

• Color pages can be used to color the sun.
• Size pages can be used to specify the size. It only accepts one page: mini, small, medium, large, and huge.
• Tilt pages can be used to tilt the sun's trajectory through the sky. There will still be a 180° angle between the rising and setting points, just like a Normal Sun. Mutilple tilt pages can be combined to make a custom tilt. "No Tilt" is equal to 0°, "Half Tilt" is equal to 45°, and "Full Tilt" is equal to 90°.
