3.2.3

Fixed an issue with !list pageNum not returning with large sound file lists. Also, fixing a test. Removing old webui files. Fixing the category display to ensure it's always in alphabetic order. Changed the Docker file to now overwrite the application.properties file if it's already there. Fixed a unit test.

Changed the DockerFile so that the images are much smaller updates. Fixed an issues with Users, in the 3.2.1 version the bot was only getting users from discord on startup and not refreshing with each REST call.
