Link a Doodad to a Checkpoint Flag (like you would a Start Flag) and
crossing the flag will replace the player with that doodad. Multiple
checkpoint flags like this can toggle you between characters.
* Azulians are now friendly to player characters who have the word
"Azulian" in their title.
* Improve Bird as the playable character:
* Dive animation if the player flies diagonally downwards
* Animation loop while hovering in the air instead of pausing
* Checkpoint flags don't spam each other on PubSub so much which could
sometimes lead to deadlocks!
SetPlayerCharacter added to the JavaScript API. The Checkpoint Flag
(not the region) can link to a doodad and replace the player character
with that linked doodad when you activate the checkpoint:
Actors.SetPlayerCharacter(filename string): like "boy.doodad"
Add various panic catchers to make JavaScript safer and log issues
to console.
