Nexus Clash

- Suggest that rejuvenate actions on other pets via Faunabond reward XP.

- Suggest that there be a trickle of XP from Aethersprite healing instead of the current zero.

xp on sprite heals was something i didn't get around to coding in b4 so factor that i guess

same as xp on aura pet kills/aoe, progression dead-ends are best avoided
