Split the image selector into two parts: character and mood/type.

[justkd]

Description

It would be more convenient to the user if the image selection input was split into two parts. It could use a layout to the position and animation selection fields.

On load, the list of image assets should be parsed, and each unique character name (left side of the ^ in the image file name) should be listed in one of the new fields. When a character is selected, then the other field should be populated with all of the mood/type options (right side of the ^ in the image file name).

This will be much more convenient as the library of characters and images grows.
