SkillUp Forever

• Needs Forever Core. Forever Core now comes in the same download, and until Forever Core has its own CurseForge page every Forever addon's download carries a copy of it, so the addon loads with nothing else to install.

For addon authors

• SkillUpForever.API is minor 5. Other addons can call Subscribe(callback) to hear, on the frame after a change lands and once per burst, that the levelling answers or the shopping list may have changed. A read with nothing to answer adds a "loading" or "none" reason as its second value, and Professions() returns a fresh table on every call, so the addon's own cache is never handed out. This needs ForeverCore 1.1.0 for its shared hub, and docs/api.md lists every function, the change names and the minor history.
