New look and minor rules changes

New and improved layout and colors! The game is much nicer to look at now. There were a couple minor rules updates to armor and shields. Armor now uses the Basic, Advanced, Next Level terminology and introduced the basic level of armor. Shields were updated to provide only 1-3 blocks. When playing the game, 6 blocks was too much. Also, updated the psionics rules requiring the roll to be < the effort.
