iconography stuff

handle non-empty loadouts without valid weapons more gracefully

micro-optimization

removed erroneous print

improved keybind closing behavior

"close" button now discards changes, "equip" will now as you'd expect equip the loadout

fix for saveload buttons

added funny little spawnmenu icons, minor appearance adjustments (scroll bars are now more consistent), internal behavior changes

added "cancel" alongside "close" to discard changes made to loadout

removed a leftover print
