Fix and tweak parrot behaviour (#13652)

* Fix and tweak parrot behaviour

Parrot stolen item now renders under the parrot's icon to make it more clear when it holds something - remember to harm the parrot to make it drop the item
Parrot adjacency checks now take windows into account - this fixes issues where the parrot would teleport behind a window to perch/steal an item
Parrots no longer try to perch/steal an item in a turf that is inaccessible to them infinitely, causing them to be stuck
Add emotes when parrot drops item
Change default parrot name to not be improper
Clean up code where possible
Correct grammar errors in parrot messages
Fix attacking parrots in harm mode not triggering specific behaviour

* Code cleanup, CanAStarPassTo atom proc

* Fix Travis

* Address farie

* Address farie 2

* fix atkverb confusion

* use LAZYINITLIST

* remove some out of scope defaults
