pAI emoticons by Willox and Messycake!

- This adds a list of emoticon choices for pAIs on the pAI OS
- These choices add small overlays on top of the screen
- Credit to Willox for the code and Messycake for the sprites.

Nodrak:
pAI's with null names now get a pick(ninja_names) name instead.
- If someone wants to make it pick from a different list feel free, but having null name causes problems down the line.
