Removed unused code in hologram.dm

Fixes displaycase when you could put a new item in it w/o first removing the first one.
Fixes parrot going through windows when getting on its perch, and some other cases of in_range() instead of Ajacent().
Fixes not being able to change transfer amount of reagent containers while buckled.
Remove unused sprites in stationobjs.dmi
