4.55.0

* Added: Link Cards. As an option, you can open a preview card when clicking on links in chat. These preview cards function similarly to the existing tool-tip or rich embed options but can provide for enhanced interaction (e.g. an embedded video player), with potential for more in the future.
* Changed: When using a custom theme with a dark background, use lighter border colors.
* Changed: Draw the FFZ Control Center and other dialogs with rounded corners.
* Fixed: Issue when clicking certain global Twitch emotes preventing the emote card from appearing correctly.
* Fixed: Issue with URL/safety data not being loaded correctly from the link service when the overall result was an error.
* Fixed: Issue with link tool-tips still appearing, but with no content, when link tool-tips are disabled.
* Fixed: Issue where (re)subscription notices in chat for multiple-month-at-once subscriptions would not be displayed correctly.
* Fixed: Tool-tips not displaying correctly in chat pop-outs in some circumstances.
* Fixed: Incorrect border styles when the chat is in portrait mode.
* Experiment Added: Set up an MQTT-based PubSub system. Let's see how well this scales.
