Patch Notes: Timers in groups, and tidier Discord event posts

Timers window

The pause menu's Timers are now grouped: World events, The Battlespire, Town raids, Seats and battles, and Resets. Each group's heading shows how many of its events are under way.
A bar of buttons at the top shows one group at a time (or All), each with its count and a green mark when something in it is live. Your choice is kept until you close the game.
An event that's under way says Now above its countdown.
The window keeps one height and only its list scrolls, so pressing a button doesn't move anything. Buttons are thumb-sized on a phone.
Elite Breach rows wear the Breach's gold, and Dagon's Breach rows its red.

Every world event post in Discord is now a card in its event's colour (Dagon's Breach, the Sea Serpent, the Abyss Dungeon, the Battlespire), with its facts laid out as fields.
Each kind of event can post to its own thread.
