Rewrite Health & Morph sections

[jaranta]

Currently the rules are not clear whether morph determines the amount of health or works as a starting point. The former is the intended reading, with the rationale that low amounts of health suit the style and mood of the game. The character creation, health and morph sections need to be reviewed so that it is clear how character health is determined.

This could be helped with some armor -- especially cybernetic implants -- giving points in health instead of adding to armor.
