Fixes lots of things not having proper icons, especially the monkey subspecies
Makes a lot of holder sprites use contained sprites properly instead of being distributed across many files
Disables picking up LF's new Vkrexi things, because they don't have sprites for it
Searched through all the bay holder icons and made sure the new ones all work, i grabbed a few from the upstream bay repo too. Held sprites for mice and construction drones!
Makes hats work properly on held drones and nymphs
Ports and implements all the new pai held sprites. Reworked pai interactions a little to allow picking them up, as well as petting/kicking/etc.
Moved pai collapsing to alt click, so it wont happen accidentally
