+ Added addon: Birthdays Widget

* Updated from PHP 7.3 to PHP 8.1
* Updated IP.Board from 4.4.10 to 4.7.10
* Updated addon: Forms
* Updated plugin: Enhanced Status Updates Widget
* New Topic display in #forums-feed on Discord (and other channels) now displays using embeds, as the old Discord integration addon no longer functions under PHP 8.1
* Fixed an issue where updating to 4.7.10 caused the mobile author pane to display on desktop when viewing topics on Elaztek Studios, Midnight, Midnight 7, Midnight 7.1, and Midnight 7.2 (including Daylight variants)
* Fixed an issue where updating to 4.7.10 caused the shoutbox to fail to load shouts, as a result of the search UI template not being updated - this has been fixed on Elaztek Studios, Midnight, Midnight 7, Midnight 7.1, and Midnight 7.2 (including Daylight variants)
- Birthdays are no longer displayed within the calendar (don't blame me, blame IPS for being lame)
- Disabled addon: Discord Integration
- Removed Killerteddy
