slave variables documentation: tired and amputees

Hi,

In the slave variables documentation, "tired" appears twice: once as health.tired (range 0 to 100) and a second time as tired alone (can only be 0 or 1). Is the second version still used? If not, then it should probably be deleted from the documentation.

For amputees, the documentation mentions amp (range -5 to 1). I think that it is obsolete. It should instead be replaced by a description of the limbs as objects arm.left, arm.right, leg.left, and leg.right. Those can either be null or have a .type field telling if the limb is natural or artificial.
