…or animated tokens

Summary

I have added option to settings that would switch usage of token texture to Actor art.
This change is transparent for current installations. Default behaviour is the old one.
This change would easily allow usage of plugin with animated tokens, which are currently not displayed inside UI.
Please note, I'm not javascript developer by trade, so please review and/or modify this PR to reflect best practices
