FullSendUI: TBC Anniversary

New
- Settings: a collapse arrow beside Move UI folds the settings window up to its header.
- Quality of Life shortcuts: instant loot while auto looting, DELETE typed in for you when destroying an item, and tooltips at the cursor. All off by default.
- Move Blizzard windows: drag the character sheet, spellbook, talents, quest log and other windows by their title bar and they open there from then on. Shift + right-click a title bar puts one back. Off by default.
- Blizzard UI: a menu bar size slider.
- Party and raid frames: HoT indicators (small squares for your own heals over time) and click-casting with modifier + mouse button combinations. Both off by default; click-casting stays out of the way when Clique is installed.
- Unit frames: incoming heals on the player and target frames and the party frames' shield look; a Show cast icon option; uninterruptible casts keep their icon with a shield badge; name and health text sit on one centered line; sharper frame text on unit, party and raid frames.
- Nameplates: tooltips on aura icons; the NPC buff row shows every buff (passive buffs hidden, or only the ones you can dispel); a tick on enemy cast bars where your interrupt is ready; optional custom cast bar colors; an execute line and an out-of-sight fade; your nameplate debuffs can follow your DoT Tracker picks.
- DoT Tracker: Priority Nameplate makes your target's nameplate bigger for a few seconds after you cast one of your Priority DoTs. Off by default.
- DoT and Buff Trackers: a None border style keeps priority icons plain, only bigger. Priority DoT borders on nameplates now keep the tracker's proportions.
- Cooldown Manager: Essential and Utility icons can show their keybinds, and "Only show when ready" (off by default) hides an icon while its spell is on cooldown.
- Resource bar: an exact power number option, and threshold lines at amounts you choose for each talent tree.
- Player cast bar: your latency at the end of a cast.
- The Action Bars settings preview now looks like your bars, with your own icons and keybinds.

Fixes
- Chat: a font size picked from a chat tab's Font Size menu now stays after a reload.
- Main action bar icons update right away after a form, stance or page change.
- Settings scroll bars move the right way; drag the thumb or click anywhere on the track.
- Choose features now lists Enemy Casts and Player Debuffs.
- Reset everything now says clearly that it resets every character on the account.
- The target frame's "Hide routine buffs" filter now shows buffs from NPCs, such as an enrage.
- The minimap no longer shows a stray heroic skull.

Smoother
- Less work when combat ends: after-combat updates are spread over a few frames, and closed Blizzard windows are no longer re-skinned after every fight or when another window loads.
- The character sheet opens with less work.
- Action bars skip repaints for key presses the game refused.
- Party and raid frame aura updates share one update per frame.
- Nameplates skip repeat work when nothing on a plate changed, and arena updates that arrive together share one refresh.
- The DoT and Buff Trackers refresh once when a fight ends.

Restart the game after installing (the addon gained a new file).
