rework assignable tunic/boots to use shipinit and hooks (#4978)

* don't put away items when equipping tunics/boots

* vb

* don't need that return

* ok i guess i'm going down the rabbit hole

* more rabbit hole

* shipinit and more hooks

* clean up

* use fewer params, add a missing condition

* make the loops make sense
