Make actor squad and NPCs that saw actor squad but not actor himself forgetful on intentional actor disguise loss

[lulnope]

This a simple improvement on the previous PR (here: #533) . Previous solution had 2 issues:

• actor squad members attacks NPCs they remember on actor disguise loss. The solution implemented here is to make them forget all NPCs on actor disguise change
• NPCs not in the npcs_memory would still remember actor squad after disguise change by actor (they saw someone from actor squad but actor himself so they're not in npcs_memory). This still resulted in random NPCs aggroing randomly as you change disguise because they saw your squadmates but not you. The solution implemented here is to iterate over db.storage rather than npcs_memory which in my understanding includes all level-objects currently loaded.

Added functionality: meat stacks have the quickest to expire meat on top (double click on stack to move the oldest meat around), proof for this functionality: https://youtu.be/e00Dyull0Ms

Sorry for mangling the PR with multiple functionalites. I forgot to switch branches, i hope it's not a big deal.
