Add HEALTH_WARM, HEALTH_COOL and HEALTH_HOT to the health enum.

HEALTH_WARM, HEALTH_COOL, and HEALTH_HOT properties are taken from the JEITA spec.

Wouldn't hurt to list the specific version of the spec these are from,

explained in "A Guide to the Safe Use of Secondary Lithium Ion Batteries 
in Notebook-type Personal Computer"
