Fixes an oversight which prevented Unathi from being able to devour big mobs such as space carp, cows, etc. This does not allow them to eat Humanoids.
Looks like carp are back on the menu boys!
update_icons(), UpdateIcon() and updateicon() are now changed to be update_icon().
Many interactions expect a target to have an update_icon(), so they should all be the same.
Also fixed some stuff that was using relative pathing, along the way.
Unathi now can no longer eat items, they can no longer swallow mobs whole, and instead they now bite chunks out of mobs instead.
Also, dionae no longer delete mobs inside them when they split.
Dionae now have a stomach organ, which means they can devour. It has a bigger capacity than usual.
Dionae can now devour big objects as well. Just pick them up and click on yourself while aiming mouth.
Unathi can now actually devour tiny items.
Unathi can now devour any mob smaller than them.
