NTFS load order, a title-sorted AddOns list, and tooltips at the cursor

- addons load in the order NTFS lists a folder, case-insensitive with an underscore before the letters, the order the vanilla corpus was written against and the one that decides which addon provides a shared library (2178)
- GetNumAddOns and the index form of every AddOn verb walk a title-sorted list that hides the Blizzard addons the server says to hide, and the character-select AddOns list is in title order (2175)
- SetPoint and SetAllPoints raise the reference's own errors for a frame name that does not exist or an omitted relative frame instead of quietly anchoring to the parent, and an explicit nil means the screen root (2176)
- a tooltip owned with ANCHOR_CURSOR follows the mouse, which pfUI's tooltip, xpbar and chat modules, pfQuest's browser and TipBuddy ask for; an omitted or unknown anchor is ANCHOR_LEFT (2176)
- a $parent name handed to CreateFrame, CreateTexture or CreateFontString expands as it does in XML, so FonzAppraiser's thirty dropdowns and pfQuest's search icon get the names they asked for (2176)
