Fix #978
* Removed theme submodule. * This should be handled by the CI. * Fixed effects not disappearing when they should (cull / repeat)
* Fixed emote synchronization * Still requires identical frame count. Will still cause freeze as it syncs. * Fixed frame effects not working on idle and talk emotes. * Characters are now repositioned after background sliding is over.
* Complete AOLayer reimplementation * Reimplemented sliding as well.
