Tweaks to Sleep behaviours, people should sleep more often...
Fixed some Desire NREs related to DesireFilter
Hacked in quick fix to turn off the "stabiliseTorso" anim bool when sleeping (cc frankeih, see HumanView)
Added an overload for Items.TryPickUpItem that doesn't rely on an animation events + callbacks
Social interactions now give a slight Mood boost rather than a "happy" buff, Happy and Sad Effects are applied using Mood thresholds instead
Added CanStowItem and CanHoldItem Conditions which actually check for the availability of valid attachment points
Fixed issue causing people to continulously try to stow a held weapon that was not stowable (rocks, etc)
