Revert true->standard change

@ln-zookeeper is quite attached to "true", and while I'm not entirely happy with it myself, it's not as misleading as the "half-orcs" reference that I changed.

Goblins are born into a lifetime of near-slavery to their larger kin, and used as sword-fodder in battle.

 Goblins perform the bulk of manual labor needed by the orcs, with the sole exception of jobs that require the brute strength of true orcs. Those the orcs revel in as proof of their prowess."
