Halcyon Druid Archetype: Spontaneous Casting not linked to archetype

The Halcyon Druid's Spontaneous Casting feature is coded up but not implemented in the archetype. Adding

ABILITY:Special Ability|AUTOMATIC|Halcyon Druid ~ Spontaneous Casting|PRECLASS:1,Druid=1

to the archetype definition should resolve this issue. Source: Adventurer's Guide
