cooldowns survive a relog, the MOTD prints, and lost channels come back

- a cooldown still running when you log out and back in keeps sweeping instead of vanishing, and another character no longer inherits the previous session's cooldowns (2116)
- the server's Welcome and Patch 1.12 lines print at login in system yellow, and a character whose General, Trade and LocalDefense had gone silent for good gets them back at the next login (2119, 2120)
- the stock Interface Options window loads hidden beside ours, so pfUI's options skin finds the real thing; the Auto-join Guild Recruitment Channel row has a real store, and a /reload no longer trips on its camera dropdowns (2115)
- the combat log words a power gain on the display scale, so MikScrollingBattleText shows +1 Rage where it showed +10; a 1.12 predicate answers 1 or nil rather than a Lua boolean, the test ColorPickerPlus makes (2117, 2118)
- a Lua error quotes a program element with a backquote the way 5.0 does, so AceLibrary's argument checks report their caller instead of raising inside the error path (2122)
