port pitbulls from legacy

[deltanedas]

About the PR

mostly the same as they were with some key changes:

• vent pitbulls have their own event instead of being tacked onto mouse migration
• if you fail to pet a pitbull it just retaliates instead of permanently making you KOS, meaning youd have to always kill the pitbull once someone failed to pet it. now they can run away and they will forget
• internally named Pitbull not Pibble
• made walter the base for pitbull to reduce copy paste and removing 90% of duplicate components from walter in an upstream file
• cargo order uses pitbull sprite instead of walter, false advertisement

Looked at the current yaml, seems fine, but I noticed one thing. Also I can see TJ having opinions on this

Still needs Game Director and general maint approval

If these are going to be added, I suggest that they do not attack anyone for no reason, IE attacking a courier just because they are wearing courier clothes, as it perpetuates a stereotype that leads to animal abuse.

Hey, so, direction here.
We'd appreciate it if this wasn't brought back from Nyano. Sorry for the inconvenience
