Hero skill trainer

Hero skill trainers are skill trainers located in Nightfall and Eye of the North.

Hero skill trainers function similar to skill trainers with some differences:
 * To learn and/or unlock a skill at a hero skill trainer, the character must spend a hero skill point.
 * Hero skill trainers will only display skills your character does not already know.
 * If the character does not already know the acquired skill, the character will also learn it regardless of their primary or current secondary profession. If the new skill is outside of their current professions, it becomes available when the character switches to the appropriate profession.
 * You can view skills for all the professions available from a hero skill trainer, regardless of your primary or current secondary profession.
 * Some hero skill trainers in Nightfall offer Sunspear rank skills to characters who have a rank of Sunspear Sergeant or higher.
