Reorganize the file_exists checks to be an array iterator instead for much less code duplication and easier ordering of priority
Reorganize desk and set_image loading on AOScene class, resolve issues with last_image setting to prevent animations from being restarted when characters talk on the same pos in succession
Apply get_image_suffix for seancestand and jurystand searches
TODO: At the moment, if you feed a .png shout, it will send the "Done" signal on the first frame (frame 0), not showing you the .png image at all. The shout code should be reorganized to allow static images to be displayed for exactly 720ms - the standard AA objection length. Usage of the timer similarly to the realizationflash.png might be possible.
Add get_image_suffix for all .gif's so that all animated pieces can be .webp or .apng instead
Expand on .webp .apng support and clean up the code somewhat
